RE: Is the market oversaturated with Pilates and Yoga.....
Re the "mind-body" mantra:
To relegate the expression "mind-body" strictly to yoga, Pilates, tai-chi, or what-have-you is specious, and if it came from the scientific community then shame on the scientific community.
Any time one is engaged in purposive movement one is engaging the mind and the body. The mind is directing a part of the body to perform that movement and innervates the appropriate neuromuscular pathways to do so. A biceps curl is as much a mind-body effort as is a sun salutation. And a step routine, a run, a swim, a challenging strength training routine, or other purposive exercise session has the potential to release beneficial hormones the same as a "mind-body" session.
Sometimes more so. I've been reading with interest the posts from people who get zero true feeling of "relaxation" from a mind-body workout, and yet get a wonderful sense of relaxation after a well-executed cardio, strength or blended workout. A lot of MindBodyites (who tend to be a fairly uptight bunch in print, I might add) usually respond by saying You're Just Not Doing It Right, but I'm right there with the ones who want traditional cardio-strength, with stretching and core stability as grace notes rather than as be-all-and-end-all workouts.
