1. Lie face down placing your hands like in common top push-up position. Keep in postion.
  2. Lift up your body and keep it straight, resting your toes on top of an Swiss ball. This is your starting position. It is of primal importance to keep your lower back straight. Keep your abs and glutes in constant tension with squeezed abs, to ensure correct position  of pelvis, tucked tailbone and straighten core.
  3. If your form breaks, stop, take a few minutes break and then repeat.

Tip: Don’t lower your pelvis during the whole exercise. Make sure that the core is not turned in any direction. Keep your balance, tensing the glutes.
