You put a lot of stress on your hip flexors when you sprint or kick. Thatâs why athletes, especially runners, soccer players, and martial artists, are especially prone to hip flexor injuries that result in hip flexor pain. Hip flexor pain is usually felt in the upper groin region, where the thigh meets the pelvis. To avoid hip flexor pain, you should pay more attention to these muscles, Dr. Siegrist explains. When you are seated, your knees are bent and your hip muscles are flexed and often tighten up or become shortened.
Walking and bicycling are good exercises for bad knees because they aren't high-impact. If you belong to a gym, the elliptical machine is another good option; the machine has pedals instead of a flat, treadmill-like surface and allows you to simulate running and walking without the impact on the joints.
Cardio exercises strengthen the muscles that support your knee and increase flexibility. Weight training and stretching do, too. For cardio, some good choices include walking, swimming, water aerobics, stationary cycling, and elliptical machines. Tai chi may also help ease stiffness and improve balance. Donât risk a fall. A painful or unstable knee can make a fall more likely, which can cause more knee damage. Curb your risk of falling by making sure your home is well lit, using handrails on staircases, and using a sturdy ladder or foot stool if you need to reach something from a high shelf. Do use RICE.. Rest, ice, compression, and elevation (RICE) is good for knee pain caused by a minor injury or an arthritis flare.
