Xtreme Fitness sells fitness and bodybuilding supplements from its storefront and also offers classes in pole dancing, Zoomba, kettle bells and some mixed martial arts. "I've personally taken a 'cycle' of everything I sell," says owner Damian Rufo of his ability to provide good, sound advice. Rufo had worked helping to design supplements before he opened his own business in 2009. Xtreme Fitness also specializes in hyper-personalized diet planning and fitness counseling.
