Seems to me like a fast tracks to shoulder issues, impingement, shortening and tightening of muscles of the shoulder girdle, rotator cuff issues etc etc. not one bit of what Piano says is based on anything other than his home made brand of bro science. Why the fuck would you continuously just do lateral raises and bent over rear laterals? How often does one actually do these movements throughout the day? Imagine all the inflammation and shit this would cause? It's moronic.
Ps I've watched him do his 3x15 second vacuums. He only holds for 10 seconds. Clear gimmick.
