In this video: Dan got a group of coaches together for a staff training session on Zoom. We talked about a lot of issues, but we started off with a discussion of neck mechanics and how the lower cervical spine behaves differently. This led us to consider the influences of dorsal-rostral mechanics and how they […]

Q & A for The 16% – Exhalation Strategies for Wide Infrasternal Angle vs. Narrow Infrasternal Angle
Question: Why is it that increased airway resistance in a pursed-lip exhale has a facilitatory bias towards external oblique activation, while decreased airway resistance with an open, relaxed jaw exhale biases more internal oblique activation? Is the difference in airway resistance even the mechanism driving the bias between the different muscle groups? #infrasternalangle #breathingexercises #billhartmanpt […]
Q & A for The 16% – Can You Make a Narrow Infrasternal Angle into a Wide Infrasternal Angle?
Question: Is it possible that a narrow ISA became wide ISA after prolonged period of compressive training(ie powerlifting)? If so, will you treat them as narrow or wide? Question 2: I’ll second this question, phrased differently can a narrow ISA present with a wide ISA measure and would to total shape of the rib cage […]
Q & A for The 16% – Wide ISA Compensations – Improving Hip Internal Rotation
Question: Based on your recent post on instagram about the end of the line compensatory sequence for a wide ISA, how would you begin to intervene with an individual who has the posterior compression in the upper posterior pelvis as well as the concentric orientation of lower glute max? In this video: I show you […]
