A move that looks pretty simple, but one that really attacks the glutes and hamstrings. I’ve watched many clients seize up with a hamstring cramp when performing this exercise. This is an indication that the hamstrings are doing to much of the work and the glutes are not doing enough.
Another thing to notice with this exercise. Watch how I have the knee of the non-working leg tucked to my chest. If you’re suffering from low back pain, I would suggest using this version. Doing this prevents back extension and emphasizes hip extension.
