I also recommend pilates for many of my clients. I would just give a little word of advice about maintaining other forms of strength training that involve your glute max outside of pilates. In pilates the glute max is often de-emphasized so that the practitioner has to use their trunk muscles more to produce movements/stabilization. This is generally a good thing. But I am seeing more and more people as of late with problems with pelvic stability because they've completely forgotten how to use their glutes related to years of pilates only for strengthening!! This group includes very accomplished and respected pilates instructors that I treat.
