Split Squat on Ball of Front Foot

This exercise is the same as a classic Split Squat, but now you want to get high up on the ball of the foot of the front leg and drive the knee as far over the toes as you can w/out pain and maintaining form. Lower into the split squat as low as you can, again w/out knee pain and keeping good form. Modify this range if needed to stay out of any pain. Keep torso upright. Go slow. Try to hold the squat for 5 seconds with each rep, challenging balance and stability in this position. 5 reps per side in a set is good. A goal is to get to 3 sets of 10-15 reps per side.
