I have been running, brisk walking, swimming, and weight lifting so far. However the past couple if weeks, I've toned down the running because my hips were really bothering me. Now even doing a long brisk walk brings on round ligaments pain. I'm really not content to do elliptical or a stationary bike...any thoughts? I can still lift weights, squat, lunge... just can't run/ brisk walk without hurting for a day or so after.
