DMSfit....The 'hidden' jewel of a fitness boutique on Chicago's NW side. Having had prior back injuries, I was apprehensive about working out with a trainer, concerned about re-injuring myself. Starting with yoga and stretching exercises, I 'graduated' to free weights, then to my surprise - kettle bells! I couldn't believe how much work I did in 30 minutes! I highly recommend DMSfit for its individual and personalized focus, affordability, and its superb trainer/owner, David Sandoval.
