then there are an infinite number of shank/knee angle combinations that satisfy this constraint. As a coach, and lifter, how does one decide which knee angle is best?
I understand that as the knee angle becomes more acute, the hamstring tension reduces (bad thing), and that if you open up the knee angle too much, then you reach the limit of how acute the hip angle can be to keep the bar over midfoot (i.e. you can't go below a hip angle of 0 degrees).
The question is this: How do you judge the correct combination of knee and shank angle? Is the "knees slightly over toes" the heuristic here?
