Question: I have been thinking about your video on shoulder flexion and your comments about how it is common for individuals to use internal rotation to finish shoulder flexion. To improve shoulder flexion without this compensation what are your thoughts on: – the Viking/landmine press? – would you opt for a single arm Viking press […]

Q & A for The 16% – Overcoming and Yielding Actions – A Demonstration
Overcoming actions and Yielding actions of muscle are sometimes difficult to grasp because of the ingrained weakness of how we learned muscle contraction in school. While useful, the model that school provided has significant limitations. If we think differently, we can refine our understanding of how muscles can magnify pressures, allow movement to occur, and […]
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?? […]
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 […]
Corrective vs. Capacity Issues
“Fatigue changes everything.” -Bill Hartman, 2008 Midwest Performance Enhancement Seminar (ugh… I just quoted myself… I’m a little sick to my stomach). Sometimes movement problems aren’t really just movement problems. Sometimes you need to address the other two parts of an effective assessment process.
