How to Choose the Right Medicine Ball

Medicine balls are commonly used for plyometric and power development drills.

The two most common types of medicine balls can be categorized by how well they bounce, high bounce or low bounce.

There’s a time and need for both, but choosing the right medicine ball can easily make or break the effectiveness of the exercise.

A medicine ball that bounces can effectively trigger the stretch-shortening cycle of a plyometric exercise, while a medicine ball with low bounce will place the emphasis on the concentric power output.

The Right Way, and Wrong Way, to Do Plyometrics

Plyometric exercises have been used for decades in both the rehabilitation and sports performance settings.

I love how plyometrics can effectively be used for power development, but are also valuable in the rehabilitation setting to gradually apply load to healing tissue while working on both force production and dissipation.

To truly perform plyometric exercises and get the most out of them, you must understand the science behind the stretch-shortening cycle.  I talk about this in detail in an Inner Circle presentation on the Science of Plyometric Exercises.

To fully maximize the benefit of the stretch-shortening cycle, you have to quickly transition from the eccentric loading phase to the concentric explosion phase of the drill.

If you perform the drills to slow, you’ll reduce the effect of the stretch-shortening cycle and decrease the efficacy of the plyometric exercise.

4 Ways to Modify the Squat So Everyone Can Perform

The latest Inner Circle webinar recording on 4 Ways to Modify the Squat So Everyone Can Perform is now available.

4 Ways to Modify the Squat So Everyone Can Perform

This month’s Inner Circle webinar is on 4 Ways to Modify the Squat So Everyone Can Perform.  In this presentation, I discuss why the squat is something we shouldn’t just blindly avoid out of fear in our rehab patients or fitness clients.  We some simple modifications, you should be able to incorporate the squat in almost anyone’s program.

This webinar will cover:

  • How different bar positions impact the body
  • Why most people shouldn’t squat with “textbook” technique
  • How to quickly screen a person and tweak their form to individualize their squat pattern

Hip Variations and Why My Squat Isn’t Your Squat

Today’s article is an AMAZING guest post from my friend Dean Somerset.  I’ve been talking a lot lately about how hip anatomy should change your mechanics and why exercises like squats should be individualized based on each person, but Dean blows this topic out of the water with this article.  If you love this stuff as much as I, check out the link at the bottom for Dean and Tony Gentilcore’s new program, The Complete Shoulder & Hip Blueprint.  This is just the tip of the iceberg of what is covered in the program.

 

Hip Variations and Why My Squat Isn’t Your Squat

In a recent workshop, I had a group of 50 fit and active fitness professionals and asked them all to do their best bodyweight squat with a position that felt good, didn’t produce pain, and was as deep as they could manage. As you can imagine, looking around the room produced 50 different squats. Some were wide, narrow, deep, high, turned out feet or some variation all of the above.

Did these differences mean there was a standard everyone should aim for, and those who weren’t there had to try to improve their mobility or strength or balance in that position? Maybe, but there’s probably a bunch of other reasons as to why 50 people have 50 different squats.

A standard requirement for powerlifting is to squat to a depth that involves having the crease of the hips below the vertical position of the knee. That’s probably the only known requirement for squat depth out there. The universal recommendation of “ass to grass” depth being the best thing since sliced bread may sound nice on paper (or in Instagram videos or Youtube segments), but it might be something that’s relatively difficult for some people to achieve, and for others it could be downright impossible, regardless of how much mobility work or soft tissue attacks they go through. The benefits of a deep squat seem to only be reserved for those who have the ability to express those benefits by accessing that range of motion without some other compensatory issue.

Let’s just consider simple stuff like anthropometric differences between individuals. Someone who is taller will have a bigger range of motion to go through to hit a parallel position than someone who is shorter, and someone with longer femurs in relation to their torso length will have a harder time maintaining balance over their base of support compared to someone who has shorter femurs. A long femur could be any femur that comprises more than 26% of an individual’s’ total height. So someone who is tall and long femured will have trouble getting down to or below parallel due to simply having the limb lengths to allow the bar to stay over the base of support during the squat motion without losing balance one way or the other.

Not as commonly known is the degree of retroversion or anteversion the femoral necks can make. The shaft of the femur doesn’t just always go straight up and insert into the pelvis with a solid 90 degree alignment. On occasion the neck can be angled forward (femoral head is anterior to the shaft) in a position known as anteversion, or angled backward (femoral head is posterior to the shaft) in a position known as retroversion. Zalawadia et al (2010) showed the variances in femoral neck angles could be as much as 24 degrees between samples, which can be a huge difference when it comes to the ability to move a joint through a range of motion.

hip variations squat

The acetabulum could itself be in a position of anteversion or retroversion, and this difference itself could be more than 30 degrees. This means the same shaped acetabulum would give someone who has the most anteverted acetabulum 30 extra degrees of flexion than someone who had the most retroverted acetabulum, but would give them 30 degrees more extension than the anteverted hips.

There’s also the differences in centre-edge angles, or the angle made from the center of the femoral head through the vertical axis and the outer edge of the lateral acetabulum. Laborie et al (2012) measured this angle in 2038 19 year old Norwegians, and found that it ranged from 20.8 degrees to 45.0 degrees with a mean of 32 in males and 31 in females.

hip anatomy squat

Now to throw even another monkey wrench into the problem, there’s the simple fact that your left and right hips can be at different angles from each other! Zalawadia (same guy as before) showed that the angle of anteversion or retroversion of the femur could be significantly different from left to right, sometimes more than 20 degrees worth of difference.

squat anatomy

All of this can have a direct effect on their available range of motion. You can’t easily mobilize bone into bone and create a new range from that interaction, so if one person has hips where the bony alignment and shape doesn’t causes earlier contact in a specific direction compared to someone else who has a different shaped and aligned hip structure, it’s going to show in their overall mobility.

Elson and Aspinal (2008) showed that there can be a massive variation in both passive and active movements of the hip across age ranges and gender differences. They showed a true hip flexion range of between 80-140 degrees (mean of 25)with no lumbar rounding, a strict active straight leg raise with no lumbar rounding range of 30-90 degrees (mean of 70), and active leg raise with lumbar rounding of 50-90 degrees (mean of 86). This means someone in their sample managed to get 60 degrees more hip flexion than someone else in the sample. There was also a range of between 5-40 degrees of hip extension too, and across an age range from 19-89 years old, that’s a notable difference, especially if you work in general populations where everyone walks into the gym and over to the squat rack.

D’Lima et al (2000) found that hip flexion ROM could be as low as 75 degrees with 0 degrees of both acetabular anteversion or femoral anteversion, but as high as 155 degrees, with 30 degrees of both acetabular anteversion or femoral anteversion. An increase in femoral neck diameter of as little as 2mm was able to reduce hip flexion range by 1.5 – 8.5 degrees, depending on the direction of motion.

So essentially, your ability to achieve a specific range of motion is as much up to your unique articular geometry as it is to your strength and mobility. In many cases, it’s entirely independent of your strength and mobility, and no amount of stretching, mashing, crushing, or stripping will improve it. In many cases, trying to achieve that range of motion that’s outside of your joints ability to achieve will cause less desirable results, like bone to bone contact and irritation (potentially leading to things like femoroacetabular impingement), or compensatory movement from other joints like the SI joint or lumbar spine.

So with as much involved with the structure as I’ve presented here, and how impactful it can be to the end result of total motion of the hips during exercises, how can you determine whether it’s a limiting factor or not? If you happen to have X-ray vision you can do a good job of this, but you’d likely be charging a heck of a lot more money than you are right now for your services.

What we have available is a detailed assessment that focuses on a combination of features.

Involving a passive assessment to assume a theoretically available range of motion and shape of movement capability, an active assessment to see how they can use that range and whether there’s a difference between the two, and then determining strength or motor pattern aptitudes for the movements can be the best tools we have at our disposal, and then coaching the movement until their face sweats blood.

By using multiple approaches to assessing available and usable range of motion, you can get multiple views into a room that can paint a broader picture of what’s available. If the person has the ability to easily let their knee drop to their chest on your treatment table and squat to the floor, there’s obviously no restriction to their range of motion. If they have trouble breaking 90 degrees, even if they move wider through abduction and external rotation, their active range is limited through multiple tests, and their ability to show you a squat shows a lumbar flexion at around 90 degrees of hip flexion as well, the odds of you mobilizing that tissue to produce a significantly bigger range may be limited.

Supported Squat Assessment


If all of these tests show a specific limitation to the range of motion consistently across all situations, it could be assumed that there would be a structural limitation versus passive insufficiency, weakness or other considerations. If active testing is limited but passive or supported assessments are fine, there could be a strength or motor pattern limitation holding the movement back.

Now sure, there’s a lot of brakes that could be restricting that range, from things like scar tissue to guarding and some soft tissue restrictions. Doing some work to help reduce that can help improve overall range of motion, but in some cases will be limited to just minimal gains. In some situations, trainers or therapists may work on improving range of motion for weeks or months and see no improvement, and in many cases the deck would be stacked against them seeing any improvement at all.

customized squat pattern

As mentioned earlier, there could also be an asymmetric structural element at play, which may necessitate an asymmetric setup for the movement where one foot is either turned out more, held slightly forward or back, or even turned into something like a one-heel elevated squat. The difference between this and a lunge is merely how far back that elevated foot is relative to the other foot, but again it’s taking advantage of potential asymmetries in structure and allowing an asymmetric set up to be more congruent with the individual.

Another way to think of it is if we have a potentially asymmetric structure yet force a symmetric set up on it, we may be creating an imbalance or compensative element in our training versus preventing it.

Bridging the Gap From Rehab to Performance

I’m really excited to announce that the online version of the Champion Bridging the Gap From Rehab to Performance seminar that we had up in Boston last month is now available!

We see so many people at Champion that have rehabbed elsewhere for months and are still doing 3×10 of straight leg raises.  It’s no wonder that studies show persistent weakness after rotator cuff repair, ACL reconstruction, and other surgeries.  We aren’t bridging the gap!  

That’s why we wanted to put this together to show how we focus on acute rehab, but understand the process to transition them to performance-based activities.

On the flip side of the equation, the assessment process and program design for someone recovering from an injury that wants to transition to strength and conditioning is also different and important to understand.  

We’ll show how we integrate strength and conditioning concepts into our rehab programs, and how we assess and design strength and conditioning programs for people follow injury.

To me, this is the future our professions need to head towards.  We can’t just perform quad sets, straight leg raises and mini squats!

 

Bridging the Gap From Rehab to Performance

champion bridging the gap from rehab to performanceThe online version of the Champion Bridging the Gap From Rehab to Performance contains 7 modules and over 6 hours of content designed to help you build better rehab and post-injury training programs.  We’ll cover:

  • Applying Strength and Conditioning Principles into Acute Rehab – Lenny Macrina
  • Integrating Advanced Rehab and Early Strength and Conditioning – Dave Tilley
  • Integrating Performance Therapy to Optimize Performance – Mike Reinold
  • Live Q&A Session with the Rehab Team
  • Performance Training Post Injury: The Assessment Process – Rob Sutton
  • Performance Training Post Injury: Program Design – Kiefer Lammi
  • Live Q&A and Demonstration of the Assessment Process and Discussion on Program Design

Personal trainers and strength coaches will benefit from learning how we integrate rehabilitation concepts into our programs to properly assess, customize programs, and advanced people into strength and conditioning programs.  Likewise, rehabilitation specialists will benefit from learning how we integrate appropriate strength and conditioning concepts through the acute and advanced phases of rehabilitation.

The Use of Non Motorized Treadmills to Facilitate Gait and The Posterior Chain

We’ve recently started playing more with non motorized treadmills at Champion and have been very happy with the results.

Non motorized treadmills have gained popularity in the fitness realm as alternatives to self-powered conditioning machines like bikes and rowers. The Assault Air bikes and Concept 2 rowers have long been popular for their ability to produce amazing workouts.

I am a big fan of conditioning machines that increase their intensity based on the amount of effort exerted. Essentially, the harder you go, the harder they push back!

These have done wonders for high intensity interval training and sprint conditioning work.

Woodway has recently developed the Woodway Curve self-powered manual treadmill. Past non motorized treadmills seemed really cheap to me, but Woodway, who makes some of the best treadmills, has really made an exceptional machine with the Curve. I started using them for sprint work with the Red Sox, but have recently been using it more and more with my rehabilitation clients at Champion.

Because it is nonmotorized, your posterior chain is nicely engaged while walking and running on the Curve. A simple period of ambulation on the Curve does a great job engaging the hamstrings and glutes. I’ve been using these in everyone with diagnoses like patellofemoral pain, low back pain, and even postoperative. We start with a slow walk and slowly build up the speed and eventually get to running.

In the video below I explain more. I’m a big fan of nonmotorized treadmills to facilitate a proper gait form and engage the posterior chain.


5 Tweaks to Make Shoulder Exercises More Effective

The latest Inner Circle webinar recording on 5 Tweaks to Make Shoulder Exercises More Effective is now available.

 

5 Tweaks to Make Shoulder Exercises More Effective

5 Tweaks to Make Shoulder Exercises More EffectiveThis month’s Inner Circle webinar is on 5 Tweaks to Make Shoulder Exercises More Effective.  Over the years, you tend to pick up on the little things that can make a big difference.  I’m always reading the latest research to find simple little tweaks that I can make to an exercise to change the desired result.  Maybe I’m trying to optimize the mechanics of the scapula, or trying to enhance EMG activity of a certain muscle, or even change the ratio of activity between two muscles.

In this webinar, we discuss:

  • Why little tweaks can make a big difference
  • Why integrating the kinetic chain into a shoulder exercise may be effective
  • How altering hip and trunk movement during exercises change the muscle activity
  • How you can put this all together and make your own functional exercises specific to each person

A Better Way to Perform Shoulder Exercises?

It’s pretty obvious that the shoulder is linked to the scapula, which is linked to the trunk.  So why do we so often perform isolated arm movement exercises without incorporating the trunk?  It’s a good question.  The body works as a kinetic chain that requires a precise interaction of joints and muscles throughout the body.

 

The Effect of Trunk Rotation During Shoulder Exercises

A recent study was published in the Journal of Shoulder and Elbow Surgery that examined the impact of adding trunk rotational movements to common shoulder exercises.

The authors chose overhead elevation, external rotation by the side, external rotation in the 90/90 position similar to throwing, and 3 positions of scapular retraction while lying prone (45 degrees, 90 degrees, and 145 degrees) that were similar to prone T’s and Y’s.  The essentially had subjects perform the exercise with and without rotating their trunk towards the moving arm.

A Better Way to Perform Shoulder Exercises?

EMG of the the upper trapezius, middle trapezius, lower trapezius, and serratus anterior were recorded, as well as 3D scapular biomechanics.

There were a few really interesting results.

  • Adding trunk rotation to arm elevation, external rotation at 0 degrees, and external rotation at 90 degrees significantly increased scapular external rotation and posterior tilt, and all 3 exercises increased LT activation
  • During overhead elevation, posterior tilt was 23% increased and lower trap EMG improve 67%, which in turn reduced the upper trap/lower trap ratio.
  • Adding rotation to the prone exercises reduced upper trapezius activity, and therefore enhanced the upper trap/lower trap ratio as well.

 

What Does This All Mean?

I would say these results are interesting.  While the EMG activity was fairly low throughout the study, the biggest implication is that involving the trunk during arm movements does have a significant impact on both muscle activity and scapular mechanics.  Past studies have shown that including hip movement with shoulder exercises also change muscle activity.

This makes sense.  If you think about it, traditional exercises like elevation and external rotation involve moving the shoulder on the trunk.  By adding trunk movement during the exercises you are also involving moving the trunk on the shoulder.

This is how the body works, anyway.  Most people don’t robotically just move their arm during activities, the move their entire body to position the arm in space to accomplish their goal.

It’s also been long speculated that injuries during sports like throwing and baseball pitching may be at least partially responsible for not positioning or stabilizing the scapula optimally.  I think this study supports this theory, showing that trunk movement alters shoulder function.

Isolated exercises like elevation and external rotation are always going to be important, especially when trying to enhance the strength of a weak or injured muscle.  However, adding tweaks like trunk rotation to these exercises as people advance may be advantageous when trying to work on using the body with specific scapular positions or ratio of trapezius muscle activity.

 

5 Tweaks to Make Shoulder Exercises Even More Effective

I’m a big fan of understanding how little tweaks can make a big difference on your exercise selection.  If you are interested in learning more, this month’s Inner Circle webinar will discuss 5 Tweaks to Make Shoulder Exercises Even More Effective.  The webinar will be Tuesday August 25th at 8:00 PM EST, but a recording will be up soon after.
