My Favorite Stability Ball Exercises: Part 1: Core Workout

Stability balls (also known as balance balls) are a wonderful tool to add variety and challenge to your workouts. They are my single most favorite piece of equipment for my prenatal, postpartum, and overweight clients due to their ability to modify many core and lower body exercises. They also add a balance challenge to any exercise allowing you to work on your stabilizing muscles.

For this newsletter I am including my favorite stability ball exercises for the core. Next newsletter will be my favorite ball exercises for the lower and upper body. Each one is rated as B=Beginner or A=for advanced. But don’t be fooled, even the beginner exercises will give you a good burn and work your body! They also indicate if they are *Safe for pregnancy. These are also amazing to help you gain your core muscle integrity back after having a baby!

If you own a Stability Ball or go to a gym where there are some, try these out and see how you like them for your own workouts!

Use abs to raise legs straight up (keeping ball between feet) until legs are straight up in the air. Use abs to pull upper body up as you reach for ball with hands and bring it back down behind your head, lowering legs simultaneously. Repeat by raising legs straight up as you raise ball with arms, placing the ball between the feet again and then lower back to the ground.
