I wish we didn't have to write so much about hips but labral tears and sports hernias seem like an epidemic.
Here are some links to help you understand the hip better and help in both hip rehab and, hip injury prevention.
There are also lots of videos on the site of hip exercises we use in prevention and rehab.
