A variation on the classic bridge, the single-leg bridge targets the hamstrings and glutes while working on an exercise ball.

Keep your arms folded behind your head and press the hips up toward the ceiling.

Hip circles on an exercise ball loosen up the pelvis by releasing any built-up tension in the hip joints. This exercise also helps you get used to sitting on the ball. In addition, it focuses on working the upper body and training your core.

Push-ups on an exercise ball target your chest muscles along with the abdominal muscles and butt to keep you steady on the ball.
