Skill Level Intermediate
Type Strength Training
Equipment Swiss Ball
Body parts Abs, Hips, Obliques

The circular arm crunch is a core strengthening exercise that targets the lower abdominals, hip flexors, and obliques.

Instructions

Lie on your back on a Swiss ball. Make sure your hips and lower back are in contact with the ball. Your feet should be flat on the floor.
Raise your shoulders and head and crunch forward while reaching both arms to the ceiling.
As you return out of the crunch, rotate your arms and head to one side in a circular manner.

Trainer’s Tips

Avoid sitting too far up or down on the stability ball. Position it appropriately at your lower back.
Keep your head in line with the rest of your body and avoid overarching at the neck.
The exercise is meant to emphasize the twisting motion. Ensure that you're twisting completely with each rep.
