what are the major purposes for using knee flexion only versus knee & hip flexion high-hang start positions?
if trying to replicate positions in the full lifts, with the bar only a few inches below the tall position, wouldn't almost all athletes be in the knee flexion, spine vertical position? if so, why add any additional hip flexion creating a position that would not generally occur with the full lifts? or would the hip flexion include lowering the bar further on the thighs?
clearly i am a bit confused on the topic.
