One-legged hamstring rolls are harder than they look! By using only one leg at a time you'll really challenge your glutes and hamstrings as well as the muscles that help you stabilize your body.
- Lie on the floor with right heel resting on ball and the left leg lift straight up.
- Press into the ball to lift the hips up into a table top position. Keep the hands on the floor to help you balance.
- Press into the ball and roll it in using the right heel, still keeping the hips lifted.
- Roll the ball back and lower the hips down, repeating the entire sequence for 1-3 sets of 8-10 reps.
