Lie on your right on an exercise mat. Fully extend your legs with one stacked directly on top of the other. Ensuring your right elbow is placed directly under your right shoulder, proceed to lift your hips and body away from the mat until you have an unbroken line from your head to your toes. Brace your core and hold this position. This is your start position. With control, drop your right hip towards the floor until it gently touches it. Reverse the movement and return to the start position. Perform all the required reps (or time) on one side before changing to the other.
