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.
âWith bad knees, what exercises can I do for leg development?â â Tony Friend. I can definitely empathize. I have also had knee issues from years of wrestling in high school and college, and bad technique in the gym early on. But, even with knee pain, you can still train hard and make progress. The goal with your program is to find the best leg exercises for your individual limitations and those that donât cause any pain.
