1. Core
Nadal’s bulging biceps and calf muscles get the most attention, but it’s his midsection that makes all his strokes, and especially this stretched-out, open-stance backhand on clay, so phenomenal. Any other player attempting to hit a ball this far from his body, with such a wide stance, would lunge forward and lose most of his power. Nadal has excellent posture, balance and overall body control. Few players have enough strength in their abs to hit such an offensive shot from such a defensive position.

2. Shoulders
Even though he’s facing the net and stretched to his limit, Nadal turns his shoulders and uncoils into the shot. This is a key point for club players: The open-stance backhand isn’t a license to do away with a standard shoulder turn. Without it, you can’t hit an effective shot.

3. Hands
Though he plays left-handed, Nadal is naturally a righty, so it’s no surprise that his right hand does much of the work on this shot. When you try your next two-hander, pay attention to your off hand. It can give you more control and power to drive the ball. Don’t let it just go along for the ride.

4. Feet
Nadal slides into this stroke and stops at the perfect time. Many club players either can’t slide on clay, or, if they can, they slide too far; Nadal has perfected the art. He comes to a stop, transfers his weight into the shot, and then his trailing leg slides along to the ready position without sending him any farther from the center of the court. He might look rugged and violent out there, but, as this image shows, Nadal moves economically and precisely. On clay, no one does it better.

5. Thighs
Do you cringe when your pro tells you to get down lower for your shots? Nadal shows how it’s done. He has enough flex in his knees to sit in a chair. His center of gravity is low and he pushes through the shot from the ground up.
