I have been working out again....pain!!!!But I gotta get this weight off and the dr. ordered I try to get back in the gym. When I do these ab exercises I extend my legs out to work on my lower abs. Well, my right hip just pops everytime I do it. I finally had to stop. My hip is so sore. Now along with fm pain I have joint pain. Anyone else have problems with joints popping especially hips?
