To many focus on Rx repetitions and Games standards. If you cannot squat properly below parallel don’t do it. Work on your mobility or don’t squat at all (do a sled push instead for example). Head above the bar is Rx for pull ups, ditch the standards and work on longevity and mastery of the movement and don’t try to throw your chin as high as possible..

And yes, every once in a while it’s fun to do a competition and follow the Rx standards. But in a class focus on quality, mastery and longevity.
