Joe DeFranco has 2 hamstring prehab exercises to share.
Upright Sled Walks
- dragging a sled with a vertical posture will hit the hamstrings better than dragging with a forward lean
- strike the ground with entire foot, think “pulling the ground back” (fully extending) with every step
Eccentric Furniture Slider Leg Curls
- you get greater glute involvement as opposed to a leg curl machine
- plus you can do these at home
Also Ross Enamait has a good unilateral option with his Hamstring sled.
