Say you're performing an exercise which forces you to have proper form and a certain degree of flexibility to perform correctly. For example, pistol/overhead/front squats. If I emphasize heavily on preserving proper form (full range of motion, no 'going around the joints' etc.) as I progress towards a heavier load, will that range of motion "cement" itself?
I ask because stretching is, to my experience, very temporal. It works well as a drill before exercise, but, stretching alone hasn't got me far. And I am desperate for some flexibility.
As a follow up: I am contemplating the idea of stretching for a long time all muscles and simply do some deep front squats etc. to really mobilize that form. Up until now, I have done with mediocre form (to parallel) and it has become like a barrier that I cannot pass. Even for light weight.
