Working on the hip, Starrett delivers a “shaman’s blow” of a test: a three-part quick-and-dirty movement drill designed to instantly assess hip mobility.
The test, of course, is not the be-all and end-all of movement analysis, because it’s staged unlike the natural movements of a squat or deadlift. But the test can very quickly identify issues including imbalances between legs. According to Starrett, side-to-side imbalance is the No. 2 predictor of low-back pain, so evidence of imbalance can be very important info.
From there, Starrett advises against some mobility techniques that put athletes in bad positions or cause numbness or pain.
“What’s the rule? Don't mobilze in a bad position.”
