going all the way down butt to floor... gives more knee pain
It's explosive movements that will cause pain and injury. Full range movements done in the relatively strict and controlled way that Sherief does it is actually better for the joints. Increased flexibility and resistance throughout the entire range.
When you do your tricep pushdowns do you stop at 90 degrees or go all the way up until your forearms touch your biceps?
