Perform a high plank position, cradling both DB in a neutral position underneath your shoulders. Place your feet in a wide position to help stabilise your hips throughout the movement. Stabilise your left shoulder whilst lifting the right DB towards your right armpit keeping your elbow tucked in. Return the DB to the start position with control. Stabilise your right shoulder and repeat on the left DB. Aim to stabilise through your hips and limit the amount of rotation. The wider your feet are the greater stability. Once you have performed right and left rep, jump both feet between the DB and extend the hips as you lift the DB off the ground and into the rack position with elbows low and tucked in. DB should be at shoulder height, extend the elbow to lift the DB above your head before returning to the rack position. Hinge at the hips and soften the knee to lower the DB to the ground and jump (or Step) back into the start position. Repeat for remaining reps.
