TheTriceps Press Plus exercise works your shoulders, triceps, chest, abs and legs.
With your knee on the floor and the other leg lifted behind you, do three triceps push-ups, keeping your elbows close to your ribs. You straighten the leg, and bring your lifted knee in towards your nose to complete one rep. Hold the knee to nose for an extra count to make it harder. Do four reps, switch side, and repeat. Do two sets total.
