You don’t have to sweat much when you do Pilates, and some people think it can’t be helping. Pilates is very subtle, concerning itself with the deep stabilizer muscles and not only the mobilizers, so one develops longer muscles and tone. Although it isn’t a spiritual practice, it provides stretching, strength and a fluidity of movement which brings awareness and concentration to the mind. It is all about strengthening your deep core. Joe Pilates observed that if people just lost weight and strengthened their back and core muscles, most back surgeries could be avoided.
