If you regularly experience pain or recurring injuries in the hips or knees, even though you stretch and do strength training, you may feel like throwing in the towel.

But according to physical therapist Sanjit Kooner, there’s one set of muscles people with injuries in these areas of the body often neglect. They’re known as the hip stabilizers, which play an important role in proper hip movement and stability. If these muscles aren’t functioning well, it can have a trickle-down effect on your knees.
