If you're not changing up your routine, ab exercises have a way of getting tedious and boring. Keep things fresh with these simple barre-inspired moves that get turned up a notch with the use of an exercise ball. The burn has never felt so good!
Beneath Your Toes
Place the exercise ball on the floor with your toes lightly on top; keep hands behind the bend of your knee.
While keeping your toes on the ball, zip legs forward. As you straighten your legs, pull your belly button down toward your spine and lower your back; return to the starting position. Do 10-15 reps.
