Step-by-step
- Take a plank position with hands on the floor and shins on a stability ball
- Shoulders over wrists, body in a straight line
- Brace your abs and pull your knees toward your chest; the ball rolls toward your feet
- Hold for one second
- Extend your legs under control back to the plank
Coaching tip
Hold the plank line; only the ball moves under your knees while your hips stay at a constant height.
Caution
Skip this move or ask a professional first if you have pain or an injury in: lower back, wrist. FitCi filters it out of your program automatically based on the injuries in your profile.
