Upper Body Stability - Positional Isometric Training - Reach Roll Lift

Positional Isometric Training (P.I.T). You need mobility to move and stability to train.

what's the origin of the coinage positional strength training. Is it FRC or is it a revised version of isometrics based on the tensegrity model of the myofascial system? or neither lol.
