The American College of Sports Medicine recently released its predictions on the hottest fitness trends for next year. For the first time in three years, Pilates did not make the list. Fitness experts cite the expense as one of the reasons the popularity of Pilates is waning. The large and costly equipment, like the Reformer and the Cadillac (even the name sounds pricey), of Pilates drives the price up where boot camps, which use little or nor equipment, are more affordable. Then there is also the degree of difficulty; one gym owner told MSNBC that the learning curve on the mind-body exercise was too steep.These days, I am a fan of both types of fitness. I have found that Pilates makes everything better, but I love the physical intensity of boot camps. I am curious which of these types of exercise you do more.
