Incorporating an exercise ball into your normal routine not only challenges your core strength and balance, but it forces you to focus on performing the moves in a controlled way.
Grab a large Swiss ball and a set of dumbbells. Choose a weight that is heavy enough so that you can complete no more than the prescribed number of reps with perfect form. Repeat the full circuit below 3 times.

Lie faceup on the floor and place your lower legs and heels on the Swiss ball to do: Hip raise: 12-15 reps Leg curl: 12-15 reps
Get into pushup position and place your feet on the Swiss ball to do: Pushup: 10 reps Jackknife: 10 reps
