Gluteus Medius

[indysteel]

I should clarify that there are yoga poses that can be used to target any of the three gluteal muscles. If you knew how to do them on your own, they could be helpful. In a class setting, however, you might be unable to do the reps of the pose or hold the pose long enough to get what you need. Plus, some of the poses (like half moon) that could be helpful take a lot of practice to perfect to the point that you can truly focus on the glutes.

So, while I think you could benefit generally from yoga (although I cringe a the name "power yoga"), I think you might be better off just doing some exercises at home or with your personal trainer.
