No more Cap'n Crunch

Gratuitous self-promoting time here on EFL. Have a look at my latest mini-article on Men's Health UK site. But I have to admit it was the MH editor that came up with the Cap'n crunch line. Why are those damn guys always so much better at writing than me...

This article was informed partly from a Dr. Stuart McGill article aimed at personal trainers that I wrote about previously. The subject of core training, while important, is ridiculously hyped (What? Say it ain't so!). McGill often points out that what should seek to achieve in training is "super stiffness" in the core. And while most people haven't a clue what that really means, nor do most care, at least about stiffness there, I'll break it down a little.

Dr. Lenny Parracino, a much smarter person than I could hope to be, said in a talk that the structure of our core serves to not only stabilize the spine, which is crucial for survival, but in order to act as a mechanism to transfer energy between the lower and upper body.

In other words, when you throw a punch or run you are transferring energy between your lower and upper body. If some of that force is lost through it's journey through the core due to lack of tension the your punch will be weaker or you'll run slower.

Or if you are in the gym deadlifting and your core is able to maintain a stiff, stable back then not only will you not be able to lift as much as your legs or upper back might allow, but the lack of stability puts excess stress on other structures such as your lumbar vertebrae, resulting in injury. Same thing for runners or cyclists, although it may take more time for dysfunction to develop.

So without further ado:


  • Don't do crunches, do Swiss ball planks

  • Avoid because... "The rectus abdominis – commonly known as your six pack – does not function primarily to bend the torso, but rather to brace the spine and transfer power from the hips to the upper torso," explains personal trainer Chris Bathke. What's more, he adds, a recent article by one of the foremost researchers on core and back health, Dr Stuart McGill, outlined how our lumbar discs can only take so many repetitions of flexion (such as a crunch) before injury and pain occur. Cap'n Crunch is a breakfast cereal. Not an aspirational nickname.

    Do instead... Swiss ball planks

    Why? They work the core the way nature intended – with little to no strain on your back. And they work it hard.

    Form Assume a plank position with your elbows on a Swiss ball and feet on the ground. Tighten your glutes and brace your core as if about to get punched. Now push your elbows against the Swiss ball while maintaining a stable torso. Three sets of 30 seconds should suffice.

    Progression Take the same position on the ball but this time move your elbows in a circular pattern (likethis chap). Again, make sure there is as little movement in your torso as possible. Do 15 seconds one way then switch directions for two or three sets.

From The Ground Up

Over the past two weeks I've had the opportunity to attend eight hours of workshops by a couple of smart fellas, Dr. Lenny Parracino of the Gray Institute, and Michol Dalcourt. The topics of discussion were human movement in a macro sense, but both Lenny and Michelle addressed the importance of foot function and how that interesting part of the body affects movement quality to a large degree.

The Gray Institute calls the foot/ankle the "switch that turns on the engine." Or in other words if your foot is not functioning optimally then movement at the knee, hip, back, and on up will be compromised, and long term may cause dysfunction.

Without proper talus (ankle) function torque cannot be converted into power in the lower body. Or in other words if your ankle is messed up it will affect how you walk or run. Common sense right?

Then think about how that may affect your fitness training. If you are running on shoes that are worn out or unstable, or if you train in the gym and in poor footwear, at the very least you are compromising progress. At worst you are causing injury to yourself. For those with flat feet or high arches, wearing the wrong shoes will hinder conversion of torque into power at the hip, which ultimately means compromising strength at the very important hip joint.

But aside from shoes if the ankle and foot is not able to function well in all degrees of motion, lacks stability, or if there is excessive fascial tension then ground reaction forces will not transfer properly into movement. For example if one's ankles do not dorsiflex or evert properly then restrictions there mean there will be increased stress on the knee in order to produce movement. Over time this may lead to knee pain and possibly injury.

But as physical therapist Bill Hartman points out here issues may not be only physiologic but neurologic. In other words long term ankle stiffness may lead to neurologic adaptations that negatively affect movement quality even after stretching the ankle. Other areas have been taking up the slack for the ankle and must now be retrained along with the ankle in order to produce good movement.



Let me explain with a little demonstration.
Take your shoes off and stand up…I’ll wait.
Now,  keep your knees straight, stay tall, and slowly lean forward until the moment you feel like your heels will come up off the floor and hold that position.  Do you feel it?
Do you feel your toes grip the floor?  Do you feel the tension move up into your calves?
In an effort to maintain stability, your nervous system turns on your calves and the deep posterior compartment musculature and on up the kinetic chain.  Many athletes have the exact same problem. 
Your mobilization and stretching may have addressed the physiologic stiffness that would prevent normal ankle mobility, but if your athlete has poor control of his center of gravity, the stiffness will persist to maintain stability.  The result is a neurologic barrier to performance and greater risk of injury.
Got an athlete with plantar fasciitis, anterior knee pain, groin pain, piriformis syndrome?
Consider looking at the factors that influence center of gravity and the associated alignment and muscular activation patterns.
Here’s a hint…start from the ground up.

Check out this video of Lenny talking about functional and structural work.

The final take home point is this. I see many people in the gym wearing shoes that appear to hinder their training. Take the time to find a great pair of shoes, or go barefoot if that is appropriate. If you are not sure what type of foot you have - flat, normal arch etc... than find someone qualified to help you. Doing so now may save you a lot of pain and money down the road. Same as eating well.

Funny how everything is connected isn't it?
