Perform this exercise with your prosthetic on and ensure it is tightly secured.
Kneel down on your hands and knees with your hands under your shoulders and knees under your hips.
Lift your knees off the floor and straighten your legs so that you are in a straight line from the top of your head to your heels.
Push your hands into the floor so that your shoulder blades flatten against your back.
Hold this position and then shift your weight onto one arm to tap your opposite elbow.
Repeat with the other side.
