This week’s questions:

When squatting, what do you believe the risk/reward is for oly shoes or some sort of heel lift. I know the obvious benefits/risks but in you’re opinion, which outweighs the other? Does it put that much more stress on your knees? Does it allow you to stack your pelvis better? Hip IR?

How would you approach working with a patient that was diagnosed with a condition related to central sensitization such as fibromyalgia or complex regional pain syndrome? Are there any specific compensatory strategies you have found to drive central sensitization (or what we may perceive to be central sensitization)?

For a wide ISA individual trying to regain his/her squat pattern, what progressions do you use after goblet/kettlebell/zercher squats? In light of Mike Robertson’s complete coach course I think the safety squat bar will be a good squat progression – allowing you to load the squat pattern and keep posterior thorax open for expansion. Do you use the safety squat bar much to load/progress the squat pattern?

How do you determine if a proxy measure of the extremity is pathological (ex. ligamentous laxity, capsular instability)? On the opposite end, how would you determine a true tissue extensibility limitation assuming you’ve maximized axial position and respiratory variability? How would you treat these two presentations differently?

Piggy-backing off last week’s question, what tests or measures do you apply to determine whether the elbow is oriented towards ER/pronation or IR/supination?

From a practical standpoint, what would be do with a narrow campo angle vs. a wide campo angle? I understand that it is a representation of the superficial helical angle that compresses the underlying axial helices, but how does it actually change our approach to gaining more variability or more performance?

Why might we use rolling activities for a wide infrasternal angle and quadruped activities for a narrow infrasternal angle ? Can you give an example of an activity for both scenarios?

So with respect to internal pressure of the guts and diaphragm with high rate of force production in say a high box jump. You’d want a diaphragm that can concentrically yield and concentrically overcome very quickly?

Please, please, please elaborate on how getting into a cut is “ER” and out of a cut is “IR”. In my myopic, acetabulum on femur way of looking at things, it seems as if “loading” should be acetabulum on femur IR and “exploding” should be the reverse. Thanks for all the content!
