Couple of things.
1. They look better than last time and that is all we can ask for.
2. Watch as you come off the box. Your weight shifts form your ass and hammies to your quads-you can see this as you rise off the box your knees come forward.
Try to keep the tension on the hamstrings.
Think about “leg curling ” youself off the box.
As you initiate upward movement, drive your head back, knees out and pull your heels into the back of your shoe.
3. Can we get some 80’s Madonna in the basement instead of that devil music?
