Start: Shoulders and head resting on a ball, with feet flat on the floor hip width apart. Knees are directly above feet. Bend your hips a little and gently turn your pelvis towards you to pause in a position where the hips are straight but the back is relaxed. Press a medicine ball or weight towards the ceiling.
Movement: Smoothly move the ball/weight overhead, keeping the back relaxed and allowing the stomach to sink towards your spine as you lengthen your body. Maintain this body position and bring the ball/weight back to the start position.
