  • Q & A for The 16% – Heels-Elevated Squat – Hip ER to Hip IR to Hip ER

    Q & A for The 16% – Heels-Elevated Squat – Hip ER to Hip IR to Hip ER

    Question: Hi there, Bill!! This is Fabrizio from Italy. Hope you are fine. I would like to know what happens when you exhale on the way down of a “squatty squat” (goblet or Zercher plus heel wedge for example). Are you actually biasing an expansion/inhaled exercise variation towards a more compressed strategy in this case?? Is a pure vertical displacement on the way down still likely to happen or will the exhale make it harder for the sacrum to counternutate?? (doesn’t in fact the exhale entail sacrum nutation??)

    Thank you, Bill. Please keep up the great work!!

    Greetings from Italy. -Fabrizio

    In this video: I explain how to avoid the compensatory breathing strategy associated with superficial muscle compression that can limit movement. I also explain how you move from inhalation/external rotation to exhalation/internal rotation and back to inhalation/external rotation as you squat. Please pardon the lack of eye contact as I was working off of two cameras.

  • Q & A for The 16% – Bones and Shape Change for Bigger Lifts, Higher Jumps, and Better Breathing

    Q & A for The 16% – Bones and Shape Change for Bigger Lifts, Higher Jumps, and Better Breathing

    Movement professionals tend to see a limited view of the human system. Focus is placed on the muscles and tendons, but the skeleton is under-appreciated. Bones bend, twist, compress and expand. They store and release a great deal of energy making them essential in the process of human performance.

    In this video: I explain how viscoelastic tissues of the movement system behave differently in different circumstances. How you can see and think about things differently when you train yourself and others.

  • Q & A for The 16% – Rotator Cuff and Scapular Muscle Activity – Yielding and Overcoming Represented

    Q & A for The 16% – Rotator Cuff and Scapular Muscle Activity – Yielding and Overcoming Represented

    Question: I was just reading through “The role of shoulder muscles is task-specific” by Boettcher et. al (2010, Journal of science and medicine in sport) which found that in 90 degrees of shoulder abduction: – trapezius and serratus EMG activation increased with isometric external rotation – trapezius and serratus activation dropped to nearly zero with isometric internal rotation at 90 degrees shoulder abduction Could you perhaps speak to how or why the body creates compression of the thorax in what would otherwise be an expansive movement (shoulder ER) and seems to allow expansion of the thorax in what would be a compressive movement (shoulder IR)?

    In this video: I explain how this finding is actually consistent with The Model in regard to inhalation and exhalation strategies via overcoming and yielding muscle actions of the scapular and rotator cuff muscles.

  • Q & A for The 16% – Belt Squat – Strategies for Pelvic Orientation

    Q & A for The 16% – Belt Squat – Strategies for Pelvic Orientation

    Question: Could you go over the benefits of the belt squat. It seems to me the belt squat would have the best application to train the squat pattern best for those who are a wide, compressed A/P with an anterior orientation of the pelvis. If performed upright would the nature of the load weighted at the pelvis help promote counter nutation and expansion?

    In this video: I explain two possible ways to execute the belt squat. One that enhances strength for powerlifting and another that enhances your ability to reduce nutation to promote counternutation and improve hip mobility. There is no right or no wrong. Just better decisions and better ways to execute the belt squat to meet your needs.

  • Padawan Lesson: Understanding Relative Motion and Orientation of the Hip and Pelvis

    Padawan Lesson: Understanding Relative Motion and Orientation of the Hip and Pelvis

    Padawan Lesson: Expand your view of what you’re measuring at the hip joint. Relative motions are occurring at all times. The pelvis should and will orient differently as you move the hip through its excursion. If we can appreciate this, we can better recognize what the body is demonstrating, and our interventions can be better targeted for success.
