Tennis players who experience aches and pains often blame the hard surface of the courts. However, the root of those muscular-skeletal aches in the lower back, groin and knee is most likely from misaligned hips.
The hips connect the upper and lower body and provide strength, stability and flexibility to both halves. Misaligned hips create incorrect movement, causing other joints, such as knees or ankles, to compensate and in turn, create new dysfunctions. Misalignments in other load-bearing joints add to the problem.

This snowball effect can eventually lead to a shoulder strain or more serious injury. Your shoulders should be positioned directly above the hips. If your hips are misaligned, the shoulders will compensate and end up in an off-balanced position that could cause problems to develop in your shoulders.
This can be problematic for tennis players because the repetitive movement of hitting the ball on a misaligned shoulder can put stress on surrounding muscles and tendons.

An imbalance in any plane will bring impurities to your posture, which over time will bring more injuries into your tennis game.

It's not important for the lower back to be flat on the floor, just feel comfortable in the stretch. Don't push your knees with your hands or force them down with your legs muscles. Let the gravity work for you and gently get deeper into the stretch. Hold the stretch for two to three minutes and use this time for relaxation, meditation, or visualization.
The supine groin stretch is such a simple and non-exerting stretch that you also can perform it in the bed at night so your hips are nicely aligned while you sleep. Functional hips will improve your movement and speed on the tennis court, decrease the risk of injuries and your tennis game will reach higher levels in a short time.
