There are many different types of Pilates exercise methods that a teacher might use and there are even different styles of Pilates that might appeal to different people. For example, some Pilates classes are centered on athletes and significant strength and flexibility is required for it. Other types of classes are geared toward the beginner and may only require limited flexibility and a minor amount of athleticism. The best thing about Pilates is that anyone of any athletic capability can begin classes. Classes can also be modified over the course of training so as to change with a person's athletic ability.
