Legs
This one isn't really about the concentric — almost nobody can pull themselves back up from the bottom yet, and that's fine. What it's for is building serious eccentric strength in your hamstrings, the kind that holds up at high speed. Kneel with your ankles anchored or held firmly by a partner, torso tall and hips extended. Let your body fall forward as one straight line from knees to head, fighting the descent with your hamstrings for as long as you can. Catch yourself with your hands on the floor once you can't resist any longer. Go only as far as you can control. A fast, uncontrolled fall defeats the purpose.
