San Diego Group Fitness, San Diego

Jeremy Dorris, a doctor with more than 18 years of fitness expertise, designed San Diego Group Fitness's boot-camp circuit classes, which he leads outdoors in picturesque San Diego parks. Breathing in fresh air, groups drop pounds and tone physiques by running through circuits of workout stations that incorporate cardio, resistance training, and agility exercises. Patrons can also peruse an inventory of nutritional supplements and workout gear.
