Even if you don’t lose a pound, you will look like you have because your posture and body shape will be stronger and straighter. Pilates will help you lengthen and strengthen every muscle in your body. By doing so you will burn calories more efficiently. Pilates combined with a healthy diet and cardio activity is a great healthy way to lose weight. Your body will also change shape doing Pilates. You will stand up straighter, your abdominals will be flatter and more engaged, and your shoulders will stack on top of your hips.
