Begin by kneeling upright on the floor slightly further than an arm’s distance away from a wall whilst holding a medicine ball in both hands.
Step one of your legs forwards and ground your foot on the floor.
Maintain a neutral spine and engage your deep abdominal muscles throughout this exercise.
Rotate at your trunk towards your rear leg, taking the medicine ball towards your hip.
In an explosive motion, rotate in the opposite direction as you throw the medicine ball into the wall.
Immediately catch the ball as it rebounds off the wall.
Repeat.
