Many people are usually given a choice between yoga and pilates. Some of them would choose yoga because they believe that this is something that they can do when they want to connect to their bodies more.
Yoga is supposed to make people get in touch with their inner selves while also working on their flexibility.
Pilates, on the other hand, is a type of exercise that some people do when they want to improve their overall muscle strength. Some people who are recovering from injury would like to do this first before trying to undergo harder exercises. Personal preferences will be enough to make people choose one over the other.
