I got a hamstring curl variation for you guys. It's called Shelcs, SHELC stands for supine hips, elevated leg curl. Higher and gets set up back of your ankle here is going to be on top of the ball just like that. And then you lie down on the ground, elbows pushed into the ground. Step one is to lift your hips up off the ground and brace your abs, toes pulled up towards the shins. As you curl underneath here, you want to keep your hips pulled up in the air just like that. Some new great progression of a standard lying hamstring curl. You're going to have a lot of core activation here to stabilize yourself from side to side.
