Pilates is a good suggestion, and also Yoga. I definitely need to be more aggressive about strengthening this area, and I will consult a doctor if I don't see visible improvement. I do have some hip issues (recurring tendonitis of the hip flexor, and more recently IT-band) stemming from an old injury many years ago but they are healing. However, that has gone on for the past few years, while the visible appearance of gluteal muscle wasting is very recent. Admittedly, I have been sitting for longer periods in the mornings with my coffee and laptop, and it's become a bad habit -- it is true that a body out of motion stays out of motion! I should set a timer for a short period and get up when it goes off, since 30 minutes easily becomes 2 hours if I'm not paying attention to the time.

I am a big advocate of classical Pilates taught by people trained in classical Pilates. Many gym "yogalates" type classes are downright injurious. I prefer mat to apparatus but that's probably because the apparatus classes are so expensive and I'm so cheap.
