The purpose of this paper is to analyze the type of motivation of Yoga and Pilates practitioners. These are believed to be two branches of fitness. To test the type of motivation that animate the practitioners, we used the Self Motivation Scale 28 (SMS 28), designed by Pelletier & al. and applied it to a group of 29 female practitioners of Yoga and 29 female practitioners of Pilates, along with a demographic survey. The results indicate that the objectives of the practitioners are muscle tone and correct posture and the main motivation is intrinsic knowledge.
