A Leg To Stand On: a look at single-leg exercises

Posted on by

As I sat down recently to design my post-injury-recovery workout plan, I had a moment of reconsidering my proportion of unilateral (one side) to bilateral exercises. Then I realized that many of you may have that same question. So let’s discuss the factors involved in adding or subtracting single-leg exercises from your program design.

Q: What is a single-leg exercise?
A: In most cases, it would be a movement in which only one foot (or other part of your lower appendage) is in contact with the ground or any other surface. As this significantly reduces the number of available options and excludes many common exercises, for our purposes we will include movements in which the other foot (or toe or knee) can touch the ground or bench but only briefly or not as a primary contributor. Now our list can include variations of lunges, rear-foot-elevated squats, step-ups, and many other movements.

So, why would we use a single-leg or unilateral exercise? Let’s discuss the characteristics that make it beneficial. The most significant aspect of a single-leg exercise is its increased demand on hip and core stability. If you only have one foot on the ground (forgetting about where your upper body may be for now), you have a decreased base of support. Even if your other toe or knee touches another surface during the movement, you still have less support than with two full feet on the ground. A smaller base of support makes it more difficult for your body to maintain balance by keeping your center of gravity within that base. This is an extra challenge for all the muscles of your leg, pelvis, and trunk. Another useful characteristic of single-leg work is the way it mirrors actual sports movements. Walking, jogging, running, jumping, bounding, leaping, and side shuffling are all single-leg activities. Can jumping be performed from a bilateral, even stance? Yes, but you’d be hard-pressed to find an example in competition. Finally, unilateral exercises offer a unique way to work on flexibility and mobility. They are a dynamic way to increase separation of the lower limbs.

That last characteristic was a major reason I decided to increase the amount of single-leg work in my own program. I noted a pattern of difficulty in both my split stance positions (one leg forward, one leg back – like a lunge) and my supine (lying on my back) active straight leg raise. I have no problem bilaterally squatting heavy weight, so it’s not a lower body strength issue. Thus I recruited single-leg movements to improve the hip-separation weak link in my chain.

One common misconception about unilateral exercises is that they are only a break from heavy bilateral lifts.  Don’t be mistaken – unilateral exercises are not necessarily less strenuous than bilateral exercises! Unilateral movements can be done for strength or size with heavy weights. This is a large part of the opinion put forth by Mike Boyle when he argued for the “death of back squatting”. Coach Boyle’s athletes do not back squat for all the reasons mentioned above and, instead, perform heavy, loaded rear-foot elevated split squats (Bulgarian split squats) and other squat variations. Coach Boyle even mentioned the research finding that the positive hormone changes occurring with heavy back squats also occur with heavy single leg work, so there is no reason to back squat.

The argument about this is too involved to get into during this post and you should definitely do your own research into the debate. The opinion at Only The Strong Fitness is that, if they can be, both bilateral and unilateral exercises should be done and the deciding factors are the individual’s needs and limitations.

You might add single-leg exercises to your program if you are experiencing trouble with your balance, your core activation, the symmetry of your lower limbs, or your mobility and flexibility. Single-leg exercises are often used in a dynamic warmup or as rehabilitation/pre-hab exercises. I prescribe them for clients or patients who have an imbalance in the strength or mobility of one leg vs the other. Let’s go over a few variations and what they might be used for:

  • Half-kneeling Cable Chop: Kneeling on one leg, other leg at ninety degrees of hip and knee flexion (bend), chopping the cable diagonally across the body with your arms. This teaches your body to stabilize itself in one of the key transitional lower body positions. Use to assist with core reaction time and strength, use to promote hip extension and posture.
  • Split Squat or Rear-Elevated Split Squat: Standing with one leg forward and one back, lunge down to touch the back knee to the ground. This promotes separation between the hips so it acts as a flexibility drill while it strengthens. Elevating the rear foot increases the separation to greater stretch the rear hip flexors and increases the difficulty. This exercise also challenges balance due to a reduced base of support. To challenge further, bring your legs more in line with each other. Be sure you can do the easier version properly before jumping ahead to a narrow base.
  • Single-Leg Deadlift/Reach: Standing on one leg, tip forward from the hips, back flat, rear leg rises as torso falls. There are many opinions regarding the proper forms for these variations. I instruct clients to keep their hips facing forward, the stance knee slightly bent, the back leg straight, and the chest up. Provides an excellent active stretch of the posterior chain on the stance leg, improves balance, and increases hip and core stability, so it’s a real multi-tasking movement.

Those are just a few of the multitudes of unilateral exercises you can add to your program. Remember, the proportion of unilateral to bilateral exercises in your specific program will be dependent on your stability/mobility needs and goals.  Sets, reps, rest, and other factors depend on the goal. Intensity is not dependent on exercise type! You can perform one or two sets of ten as part of your dynamic warmup or mobility drills, or you can use them in between sets of other exercises as active rest. You can fix an asymmetry in your lower body by using them in an assistance exercise pattern, or bulk up using them with heavy weights as a main strength movement. Always be sure to use a full range of motion (as with any other movement) and you should see great results from adding single-leg movements to your program.

The Absentee Client (an enlightening rant in the key of @#!!&*#@!)

Dear YOU,

“You can do it!”

There’s an important word in that sentence – YOU. Where are you? Why aren’t you here, at our appointment? I set up the weights ahead of time and that helped make ME a little stronger, but the bar sitting on the rack isn’t making YOU any stronger. For us to achieve the goals you stated you would like to achieve, YOU need to be doing SOMETHING!

Let me be a little more clear: I’m not saying that you must use my weights, or my gym, or even any “gym” at all for certain goals. We may develop a fitness plan that involves bodyweight and outdoor activities. It is irrelevant to my point. Regardless of what the activities, exercises, or therapies are, YOU have to DO them at some point. Knowing the plan and doing the plan do not get the same results.

How do we know this? Because I enjoy teaching, here’s a simplified definition for you:

SUPERCOMPENSATION = your body’s ability to attain a post-workout fitness level greater than the previous fitness level, in order to be ready for the next workout.

Supercompensation sets in after the workout’s recovery period. That higher level will be sustained for a certain amount of time, depending on the individual, and is usually a few days. If you train again within the supercompensation period, you will again improve your fitness level, and so on up to peak genetic potential. If you do not train again within the supercompensation period (wait too many days before another workout), your body will say “use it or lose it” and you will regress back to your initial fitness level.

Stimulus, recovery, supercompensation, return to baseline

This is a long-winded way of saying GET GOING! For results to happen, you have to put the time in. And then you have to put the time in AGAIN, probably a few days later, sometimes even the next day and the next day after that depending on whether you are a novice or advanced athlete. Corrective exercises and rehab should be done every day or every other day. (There will be more information on this in a future follow-up post on periodization. I haven’t forgotten!).

Where is this all coming from? The recent slew of people telling me they exercise once a week and their goals are to lose 40 pounds, have ripped arms, have a six-pack stomach, and get back to playing a full-contact collision sport on the weekends. I’ve had people say they need to lose 30 pounds and want to train with me, but they only want to see me 2x A MONTH. They’ll “just go do stuff on their own”, like walk around the park on the weekends (if they aren’t too hung over), and check in with the plan twice a month for more advice. “Starting next month, because I don’t want to start this month, what with work and all.”

Let me know how that works for you….

Some people come to me with financial difficulty in affording a trainer. I understand. It’s your money to spend how you will. If you can afford it, investing in your health, pride, and happiness is a pretty good start, I’m just saying. (Despite the unfortunate realities of income vs the cost of better quality food choices and gym memberships, etc, the ability to improve your life via exercise should not be the sole realm of those who can afford a personal trainer. There are less expensive options.) Regardless, walking in the park on weekends is not enough stimulation to cause your body to improve. You are not 80 years old. Up the intensity, grandpa! Running 2 minutes to catch your train is not sufficient activity for the day. There is no magic pill for your goals. I repeat, THERE IS NO MAGIC PILL FOR YOUR GOALS. Whether or not you see me, whether or not you join a gym or an exercise class, you have to BE THERE. Show up and put in the time!

Despite my personal feelings towards group fitness classes and the gimmicks they use, they at least work at getting a lot of people off the couch and moving. I’m not going to tell you that you have to enjoy lifting weights. Many people find it tedious and boring (not anyone who experiences my witty banter, of course) and have no motivation to stick to a plan like that. That’s fine. If it makes you show up and participate, I’ll accept it for now. We can slowly wean you off that nonsense by explaining exactly what going to spin 2 nights a week and “rock hard abs 8 minute video” are NOT doing for progressing you towards your particular goals and ARE doing for progressing your physical therapist’s and orthopedic surgeon’s bank accounts (that’s a whole other post). And most people find they DO really enjoy lifting weights when they see the actual results that happen over time and the confidence that comes with being stronger and fitter.

Stop making excuses. Stop saying work got in the way. Don’t say you can’t find the time. Make the time. It may require a lifestyle modification. If the desire is really there, you will find a way. You might need to make a way. If you haven’t, you don’t really have the desire, you just like to pretend you do. I won’t program for someone who plans to exercise twice a month. These are YOUR goals, not mine. To summarize: GET YOUR A** IN HERE.

Love,
Only The Strong

Applying Corrective Exercises – Knowing is half the battle

Posted on by

When I evaluate a client or athlete, I’m searching for faulty movement patterns.  A faulty movement pattern may be something like a squat that can’t be done without the lower back rounding (lumbar flexion) or a lunge where the knee falls in (knee valgus).  They are pieces of movement that are usually unsafe or compensatory, and need to be corrected in order to safely and effectively progress with a workout.  Often, there is complete unawareness of the faulty movement because it is what feels natural.  As we will see, this is a large part of the success or failure of a corrective exercise.

In the words of Dr. Charlie Weingroff, DPT, ATC, CSCS, from a recent web lecture he presented, “corrective exercise is getting good at what we are not good at.”  In order for a movement or exercise to have the nature of being “corrective”, it needs to correct something – namely, a movement we are performing incorrectly or poorly.  In conjunction with this is the fact that – in order to know something is being done incorrectly – there needs to be a standard of what is correct.  Myself and many other practitioners utilize the Functional Movement Screen (from Gray Cook) as a comparison tool for standards of non-painful movement, though it is not the only acceptable method.  The FMS helps present what an end-state posture or correct movement pattern should look like as compared to the client or athlete’s movement.

Once the faulty movement has been assessed against the standard, it can be corrected.  Step one is making a person aware, mentally AND physically, of the incorrect movement.  As I said before, it is highly likely that this person was totally unaware of the compensation or restriction as it is just their natural way of moving.  It is a subconscious dysfunction.  But it is not enough to say “Hey, did you know you shift your weight to the right when you squat?”  The corrective exercise chosen to repair the subconscious error should bring the person to the barrier or limit of their restriction so that they can also FEEL things being done incorrectly.  You will have gone from a subconscious dysfunction to a conscious dysfunction, and this is the big step in being successful.  A physical awareness of the error allows the person to correct themselves through frequent unsupervised practice and to relearn appropriate movement.

Now, like Charlie said, the exercise needs to have corrected something.  We must reassess the deficiency.  Corrective exercises can usually be done every day, as they don’t really require much recovery time.  This allows for much consistent practice on the part of the client or athlete.  After a week or two of practice, re-evaluate; and if the faulty movement is corrected, there is no need to continue with the corrective exercises.  The person has gone from conscious dysfunction to conscious function, and is one step away from lasting success.  Progress with the next step of the workout plan, whether that is to perform conditioning or more standard exercises, or move on to another pattern that needs to be corrected.  After another brief interval, we check the first pattern again.  Has it stayed corrected?  If the proper corrective exercise was selected for the dysfunction, it was applied in the appropriate way, and the person was able to feel the dysfunction to practice self-correction until it was automatic (subconscious function), there should not be a need to continue doing it.

Corrective exercises should not be never-ending stories.  When subconscious dysfunction has progressed to conscious dysfunction, correct movement can be practiced as a conscious function until it is a subconscious function.  At that point, the movement should no longer be an issue and you have achieved lasting success!

ACTIVE REST – Dr. Crystal Joseph, D.C

Posted on by

Welcome to ACTIVE REST, the latest addition to Only The Strong Fitness!  This is a new section consisting of interviews with intelligent and experienced members of the health and fitness community.  This section may eventually be turned into a podcast, when I figure out how to do that, but until then my humble paraphrasing and editorial skills will have to suffice.  For the first installment of ACTIVE REST I sat down and spoke with Dr. Crystal A. Joseph, D.C.  Dr. Joseph is a Certified Chiropractic Sports Practitioner and a Certified Applied Kinesiologist.  She has a background as an All-American high jumper, and is also a dancer.   She was kind enough to answer my questions during some time on the stationary bike!

 

OTS: To be honest, I usually refer to you guys as “chiro-quack-tors”, no offense.  Can you flesh out your background for us and what makes you different?  What the heck is an Applied Kinesiologist??

DCJ: People don’t necessarily know what a “chiropractor” is or can be.  They may only be familiar with the stereotype of “cracking backs” and having to endlessly return for more appointments without a foreseeable resolution of the problem.  There are some old school doctors still stuck in this approach who do things by rote and are not actively continuing their education or digging deeper for the root of an issue.  I believe in taking an integrative approach, which is what applied kinesiology is about.  It’s not just about the spine – I take into account all body systems.  In addition to a physical evaluation or adjustment that will include posture/gait analysis, breath assessment, full body neurological tests, deep tendon reflexes, blood pressure, and muscle testing, you will be asked to fill out a nutritional questionnaire and we will delve into the level of stress in your life, your level of activity, and so on.  This is all to determine which system or systems should be addressed in your treatment for a total body resolution of the problem.

OTS: Yes, too often it seems like practitioners are just treating symptoms, not the underlying causes.  I like the comprehensive approach and try to apply it when dealing with clients.  Is there any body system you don’t touch on?

DCJ: Often patients come in for a musculoskeletal problem and I find other issues in the evaluation, especially in the case of athletes.  They tend to feel everything is just physically based, but stress can put other body systems “out of whack”.  I also frequently have patients referred for non-musculoskeletal problems, like PMS or indigestion, and I am able to help them because of my training in applied kinesiology and in naturopathic medicine.  In kinesiology there is a belief that the body speaks a language and thus the relationship of the muscles to the functionality of systems and organs have been mapped out.  For instance, during lingual testing of supplemental vitamins and through the nutritional questionnaire, I may find that a patient is lacking in a certain nutritional need and that is causing a body system to malfunction, which is then causing a musculoskeletal discomfort that can cascade through the body.

OTS: Example?

DCJ: Let’s look at a patient that comes in with a complaint of neck pain.  A visual exam shows they have a forward head posture with rounded shoulders and need to stand up straighter and spend less time hunched over their computer.

OTS: Shocking…

DCJ: I know, I know…  So, upon further physical exam, I find that they have very tight quadricep muscles, pulling their pelvis into anterior tilt and causing hyperlordosis and hyperkyphosis (increased curves) in the spine – the end result of those being forward head posture and neck pain.  Without the addition of information from other biological systems, I might just have them work on their muscle flexibility.  But tight quads may not just be a stretching issue.  Your quadricep muscles are also affected by the level of absorption of minerals in the small intestine.  Delving into their eating habits and stress levels may determine they are not getting what they need nutritionally.  For instance, as our age increases, our level of stomach acid production decreases, meaning we break our food down less and have less opportunity to get the vitamins and minerals needed.  This patient may need to supplement their diet with probiotics or HCL (hydrochloric acid supplement to help break down food in the stomach) to better absorb the minerals they were missing.  There is then less effect on their quadricep muscles, which will have increased flexibility, allowing their pelvis to realign correctly, ridding them of hyperlordosis in their lower back and hyperkyphosis in their upper back.  That makes it easier and more effective to use corrective exercises or manual adjustment to realign the forward head posture and relieves them of their neck pain!

With that said, I do refer patients to outside sources if necessary.  Besides biological systems, I find it very useful to stay in touch with those who can help the patient deal with mental and emotional issues that may be causing a physical complaint.  In the case of an athlete, that will be the athletic trainer, the coaches, a personal trainer, or possibly a school counselor.  These people are in constant contact with the patient, know them very well and may be close with them, and can assist in reducing or removing the cause of the stress.  It’s often a team effort.

OTS: Agreed.  As an athletic trainer I am in constant contact with PCPs, orthopedists, and other specialists, including school counselors.  Athletes especially tend to ignore the effect mental and emotional stress can have physically.  As a personal trainer, I need to pay close attention to a client’s work and home balance and it is often difficult to convince them to re-balance.

DCJ: For me, that’s what it is all about: knowing what a person does or is trying to do and breaking down what they are saying into what their hindrance is.  Then, it’s up to us guide them and get them to BALANCE themselves, whatever that may mean and by whatever means necessary.  I like to impart to them some wisdom that was given to me by my mentor, Dr. Eugene Charles, which was that “health is a process, not an event”.

OTS: Very true.  In fact, I think I’m going to steal that quote for future use!  Too many people are under the influence of commercial media, where everything has a quick fix and problems are solved in 30 minutes or less.  10 minutes for abs, etc.  I spend a good deal of time helping clients and athletes understand the process and why we may be starting our route in an unexpected or seemingly unrelated body area.  It’s good to have another voice in the mix passing on the same idea.

DCJ: It’s great to have personal trainers to refer patients to that “get it”.  It’s also great to have you guys on the team as extra guidance for myself.  I’ve had Personal Trainers help me planning my own workouts, targeting the real roots of an issue and adding functionality, and that is a large part of what has helped me continue as a competitive runner.  I transfer those ideas to my patients, especially the functionality of an exercise.  I have worked with personal trainers to have a new mother exercise with off-centered weight loads to help her get better at handling the shifting weight of a baby.  It’s not just “crunches”; it’s a real, useful, and safe core/trunk exercise that will really translate for her.  You guys keep up-to-date on all of that stuff and are a good conduit of that information for me.  It’s key as a professional to sometimes have outside guidance and be integrated as a team with professionals in related fields.  We each add a layer of expertise for the patient/client to be able to achieve a higher level of accomplishment that he or she can’t do alone.  It may be a nutritional aide, a stretching technique, an agility drill, or a balance and proprioceptive technique that will assist them in accomplishing an activity of daily living.

OTS: Absolutely true.  When I saw you for my hamstring issues and was handed a nutritional questionnaire, it was rather eye-opening, and now it seems pretty silly that I hadn’t thought much about that stuff before.  So thank you for that.  And thank you for your time answering my questions and helping OTSFitness Readers get more familiar with the ideas behind good chiropractic medicine and Applied Kinesiology.  I’ll let you get on with your workout now.  Thanks so much!

DCJ: You’re very welcome!

Dr. Joseph is located at 200 West 54th St, between Broadway and 7th Aves, in NYC.  She can be reached at 917-828-6733 or DrCrystalJo@gmail.com for appointments.

 

An Apple A Day…

Posted on by

You know the rest.  But no, this isn’t a nutrition posting; it’s actually some information about shoulder health and safety.  As these exercises can also be done for hypertrophy to improve a bodybuilders physique, the topic has been double categorized under “Fitness Tips” and “Corrective Exercises”.  What I’m writing about today are exercises for your Rotator Cuff musculature.

What is the Rotator Cuff?  It is a group of 4 muscles in and around your shoulder joint.  The area referred to as the shoulder is complex and involves multiple joint interfaces, but for our purposes we will be referring to the glenohumeral joint (the ball-and-socket), as that is what the muscles primarily affect when they act.  Those muscles are:

Supraspinatus: acts to abduct your arm (raise it up to the side)

Infraspinatus: acts to externally rotate your upper arm (turning out your pockets)

Teres Minor: also externally rotates your upper arm

Subscapularis: acts to internally rotate your upper arm (wrapping your arms around yourself)

View of the RC

Collectively known as the SITS muscles, they act together to stabilize the “ball” (humeral head) of your upper arm (humerus) in the “socket” (glenoid fossa) of your shoulder blade (scapula).  When these muscles are injured or weak, the ball can shift around in the socket, causing further weakness and instability in the control of your arm.  Often, a chronically unstable shoulder leads to injuries such as subluxations, tendinitis, or neuropathies.

Who wants that?!  No one!  So what should you do to ensure a stable shoulder joint and prevent putting your orthopedist’s children through college?  Here are a few exercises to add to your workouts that should be done every other day or so (every day if you have a history of ball-and-socket problems).  They should be done for volume (high reps) with a lower intensity (weight) because these are postural muscles, programmed for the high endurance job of maintaining the same position all day.  They should also be done at the end of the workout to avoid them being too fatigued to assist you in correctly executing your upper body exercises that day.

1) Empty Can (for supraspinatus): stand upright with good posture, arms down at your sides.  As you raise your arms up and out on a 45 degree angle (not straight to the side, not straight out in front), keep your thumbs pointed towards the ground (as if you were emptying a can of its contents).  Do not raise your arms higher than shoulder height and, in fact, it’s not necessary to go more than 30 degrees up because that is when your deltoid muscle takes over the movement from the supraspinatus.  Traditionally the exercise is done to shoulder height, though.  Perform 3 sets of 10-15 repetitions.  Add weight conservatively as the exercise becomes easier.

2) Side-Lying External Rotation (for infraspinatus/teres minor): lie on one side on the ground or a bench, say your left side.  Have a rolled up towel held under your right arm, against your side, to keep your arm from being flush against your side.  This puts the shoulder in a better anatomical position for the exercise.  Begin with your right elbow bent to 90 degrees and your forearm across your abdomen.  Keeping your upper arm in line with your torso the whole time, roll your right forearm out away from your torso, towards the ceiling and then slowly back down again.  Do not rotate too far – if your right hand is going behind you, you are way too far.  Perform 3 sets of 10-15 repetitions.  Add weight conservatively as the exercise becomes easier.

3) Standing 90-90 External Rotation (for infraspinatus/teres minor): this is one of the many variations on external rotation exercises.  Stand upright with good posture (shoulder blades back) with your back against a wall.  Raise your arms up to 90 degrees (but not more) against the wall.  Bend your elbows to 90 degrees and place your forearms and the back of your hands flat against the wall.  Slowly let gravity rotate your arms downwards so your palms are facing the floor (elbows still bent) and then actively roll them back up to the wall again.  Perform 3 sets of 10-15 repetitions.  Add weight conservatively as the exercise becomes easier.

It’s rare that anyone needs to exercise their subscapularis, as most people’s internal rotators are overly developed and tight.  But for the sake of being thorough, here is one exercise.  Do not overdo it.  It is far more common to need work on the external rotators mentioned above.  Always do more external rotator work than internal unless you have a diagnosed injury.

4) Standing Cable Internal Rotation (for subscapularis): stand with a cable machine to your right side, cable in your right hand, rolled up towel (again) under your right armpit.  Maintaining the same good posture and arm positioning as for the Side-Lying rotation exercise, pull the cable and rotate your forearm in towards your body it touches your abdomen.  Then slowly release the cable back out again.  Your elbow should always be bent to 90 degrees, as if your forearm were sliding along an invisible table top in front of you.  Do not let the cable yank your arm out, and do not rotate out to the side past your torso.  Perform 3 sets of 10-15 repetitions.  Add weight conservatively as the exercise becomes easier.  **This can also be done as another external rotation variation if you turn and face the other way.

Now you have a starter packet for shoulder health and safety.  Not only will these exercises help keep you out of the doctor’s office, but they will make you stronger.  When your weightlifting hits a plateau, make sure you are keeping up your rotator cuff strength, as that step has been shown to reinvigorate the upper body’s ability to handle heavier weight!  Stable little muscles make bigger muscles fire more effectively and keep optimal alignment for torque, which means you can push more people around.  Happy lifting!

Corrective Exercises

Posted on by

Corrective exercises serve to counteract the bad habits we fall into with regards to posture and movement.  They can relax tight muscles and reactivate lazy ones.  They help resolve chronic injuries and prevent new ones by realigning our spine and keeping joints moving efficiently.

One simple corrective exercise that can be performed anywhere easily is a chin tuck.  It involves pretending your head is on a platter and sliding it backwards, giving yourself a double chin.  You should sit up straight while performing this exercise.  This helps loosen the tight muscles at the base of your skull and regain mobility in the cervical spine that is lost from slouching.  It can be done in sets of 10, 2-3 times a day for less neck pain, shoulder pain, and headaches.
