Exercise ball pike push up

Start in a push-up position with your hands on the floor and your shins resting on the stability ball. Engage your core and lift your hips up towards the ceiling, rolling the ball towards your hands. Keep your legs straight and your body in a pike position, forming an inverted V shape. Bend your elbows and lower your upper body towards the floor, keeping your head in line with your hands. Push through your hands and extend your arms to return to the starting position. Repeat for the desired number of repetitions.
