HOW: Begin this exercise on your back with a swiss ball resting on your stomach. From here, straighten your arms and bend your knees while bringing your feet up off the floor. Engage the core by bringing the belly button down to the spine and gently push your arms into the ball to create tension through your abdominal region. Hold for the recommended amount of time.
FEEL: You should feel your core muscles working.
COMPENSATION: Avoid allowing your back to arch while performing this, maintain a strong core position.
