Holding a light dumbbell with both hands, stand with your feet hip-width apart. Bring the dumbbell up to the left side of the head. Next, swing the dumbbell down towards the outside of the opposite hip. Continue to alternate between lowering and raising the dumbbell across the body, as if you were splitting a piece of wood!

Press the dumbbell up and rotate the arms outwards, then back in until your arm is by your ears and exhale Return the dumbbell slowly down to your shoulders in the same manner and reset your breath ready for subsequent reps
