I had neglected my legs for a long time, and now I'm trying to make sure that I work them just as much as everything else. Doing squats and lunges have started absolutely killing my glutes and hamstrings even if I go fairly light. I can stretch my hamstrings just fine, but I can't seem to find a single stretch that helps my glutes. Any advice on a good stretch for them? Where my ass meets my legs is killing me today and I've gotta do something to help it.
