Come into an all fours position on an exercise mat with your hands directly under your shoulders and your knees directly under your hips. The palms of your hands should be flat to the floor, directly under your shoulders with your fingers pointed forwards. This is your start position. From there, rock slowly forward moving your shoulders over your wrists and keeping your palms in full contact with the floor throughout the movement. Then move slowly backward, doing the same. Keep the elbow joint as straight as possible throughout. Repeat for the recommended amount of time.
