The way you feel in your body influences you on a daily basis, whether you are aware of it or not. It affects your mood, the way you carry yourself, your relationships (to yourself as well as to others around you) and your general outlook on life. We only have one body in this life, so we better take good care of it. 
Pilates is for every body, no matter the shape or size, no matter the limitations, no matter the previous experience or age. This practice can help you break free of the habits that cause you to feel poorly, and help you train towards a better posture, stronger, more mobile and flexible body.
