You apply Pilates in everyday life, like how you sit, how you walk. You've heard a lot of people complain about back problems; it is because these people walk incorrectly with the last vertebra of their tailbone. They stick it out instead of pulling it in and down.
You can say what Pilates is in three words. Stretch with Strength and Control. And the control part is the most important because that makes you use your mind.
