The Ready State Virtual Mobility Coach is like having a virtual Kelly Starrett in your pocket.
You want to have your elbows along the body when doing push ups.
Having the elbows out puts alot of stress on the rotator cuff.
Keeping the elbows close to the body allows you to engage your chest, triceps, lats, traps, and biceps while protecting your shoulders.
Contract your stomach, butt, hands shoulder width apart.
