I am having a problem with my right hip where something is "catching" when I go from my leg being fully bent to straight. It's quite painful and I can actually feel the tendon (or whatever it is) shift over the bone. If the movement is slow and deliberate it's not a huge problem, but anything quick or explosive is troublesome. I'm going to see a ortho doc next week, but in the meantime I don't want to stop working out.
Are there any alternatives to the tuck-up that I could substitute until I get more concrete direction from the doc?
