It is very hard to teach a Pilates class in most of the "mass market" gyms - in the way it should be taught. The gyms want it cranked up and styled to keep the clients coming back, and after teaching the class for a while, and what with the different levels of exercisers you get, sometimes I would add big balls, small balls, magic circles and bands, but would still do the traditional exercises. I did this because I felt the clients would get bored, after doing the same thing week in and week out. I actually would stay in the front of the class and perform the exercises, because I felt they needed the visual cues to do the exercises, but I did "talk the walk" meaning walking them through what they should and shouldn't do and what to be aware of. Some people like to have you walk around and others don't, so what's a trainer to do? I tried to be very specific in the cues, and if I saw something that didn't look right, I would let them know in a nice way. I never had anyone injured. But I also have a fitness background, have worked with rehab clients and know how to help keep them from getting injured. The average "regular" gym is not an easy setting to be able to get into the specifics of what Pilates is really all about. I also would give them handouts, too, to teach them more about Pilates history and what the exercises were for, etc.
