Many people with pelvic pain are asked by doctors if they ever danced. I certainly have been asked this. This is because dancers tend tend to have loose ligaments, do wacky things with their pelvis, and have horrible posture (especially, ballet dancers). This article summarizes things that anyone can think about in terms of overall alignment and what muscles might be imbalanced for better pelvic function. If you do strength training at a gym, I would think this information would help you create a better program than you might on your own or with a trainer giving you a "regular" fitness plan.
