We use many different exercise variations with the runners and triathletes we work with, to target the often under conditioned Glute complex (butt muscles).
Yesterday at the track, we filmed one of the female triathletes we work with, performing this powerful alternative to the classic Single Leg Squat - using a tennis ball.
The reason why we use this specific exercise in place of the Single Leg Squat is that (when performed keeping a straight back) it places the emphasis on loading through the hip, rather than the knee - loading the quads.
Try it out - You can substitute the ball for anything you want!
