Continuing our flashback series, joining me on the show this week is Zac Cupples, rap battle and PT extraordinaire. In this episode, Zac and I unpack how to decide whether your client should focus more on squatting vs. hinging, how to decide on the specific squat or hinge variation that should be in your client’s program, and how inhaled skeletons, exhaled skeletons, and the heel wedge tie into the big picture. All in all, this episode provides some much-needed clarity on these biomechanics and movement-based principles.
