is there literature about power lifting and weight lifting and the hamstring curl or knee flexor capabilities?
Most they do squat, deadlift, goodmorning, straight leg deadlift, but it seems the leg curl of knee flexors are less trained. For instance biceps femoris has an aponeurosis and the knee flexor could be underdeveloped.
In practice I see people squating 100+ but leg curl with very low KG.
