Step 1: Lie on your back with your legs extended, arms straight overhead, and hands gripping a Swiss ball (you could try this with a pillow folded in half if you don’t have a ball).
Step 2: Raise your arms up with the ball, keeping a slight bend in your elbows, while simultaneously raising your legs up to meet the ball in the middle.
Step 3: Grip the ball with your legs by pressing your knees in slightly and lower your body back to a reclined position, keeping the ball between your knees.
Step 4: Repeat the motion, this time transferring the ball from your legs to your hands.
Step 5:Repeat 12-15 times.
