NO HANDS, HAMSTRING CURL This one is very challenging. When you have your arms on the ground, you can get away with being sloppy. This variation will ensure that you focus on symmetry. Dig both heels into the ball, engage both hamstrings equally, and perform efficient reps. Important note: There’s nothing wrong with having the arms down, as long as you focus on quality. #rcperformancetraining #trainwithrc #rcsoccer #thercpodcast | RC Performance Training
