The stability ball creates an unstable environment for combining two opposing movements in this full-body exercise.
Chest, Core, Hip Flexors, Shoulder Stabilizers
Take up a plank or push-up position with your shoelaces on top of a stability ball, toes pointed to hold it in place. Your spine should be parallel to the floor, with shoulders retracted back.
- From the starting position, perform a push-up, bringing your chest to the floor while keeping your body straight and your neck in line with the rest of your spine.
- Once you have completed the push-up, keep a neutral spine and straight legs as you pull up through your belly button and bend at the hips to perform a pike-up. That is, press your hips straight to the ceiling, keeping your weight in your hands as though doing a handstand.
- From the top of the pike, slowly bring your hips back down to the starting position, with spine parallel to the floor. Continue alternating push-ups and pike-ups for an entire set.
