change can take months to happen. it’s frustrating to be that long, but sometimes it can take one session or it can take the better part of a year. 

in any case, examining your movement patterns will speed up the process and doing hip openers and stretches with band preferably will also help a great deal beyond just smashing. 

case in point – it took me a good 4 months of hip openers and smashing to get from bad squat to almost ass to heels. but i then plateaued there for many months until i played with Ready to Run’s air squat test (8x 20s AMRAP air squats, RI 10s, with good form, and below horizontal at deepest part) for a few weeks. imparting movement in this manner really greased my squat ability and now i find i can get pretty deep without mobs. 

i just took Original Strength Foundation I a week ago. i find that the rocking exercises are doing great for my hip mobility as well.
