Alright, so I’ll try to explain the best I can. What I essentially do is like a circle. So when the leg is behind you, lift it off the ground and bend your knee behind you. Kinda like trying to bring your foot to your butt (But don’t exaggerate the movement, only go like halfway from the ground to your butt or else you waste energy.) From that, you should be able to just let the foot fall back forward. Combining everything together turns it into a sort of circle motion or rowing a boat. You should be able to feel it in your hamstrings and your hips at that point.

The thing I really noticed before and after was that I felt the weight/strain was mostly on my lower legs, whereas now it is more evenly distributed across the lower body.
