Thomas Edison declared that genius is 1 per cent inspiration and 99 per cent perspiration, a fact he discovered while inventing the volcano. Work up a healthy sweat with today's Groupon: for $20, you get 10 classes at Studio Fitness (a $70 value).

Studio Fitness inspires healthful bodies and energized spirits with an eclectic roster of classes. Patrons yearning for interval training or rationed water breaks can enlist the military training of boot-camp workouts, and Slim & Fit classes summon aerobic sequences and light weight exercises to jumpstart metabolisms. The fitness centre also unites sentient minds and limber bodies in its wood-panelled studio in which a series of Ashtanga yoga poses teaches breathing techniques and helps increase flexibility. For invigorating sweat sessions, customers flock to Daredevil 101 seminars or to Turbo Kick tutorials, where ceiling-sweeping foot jabs torch calories to a cardio dance soundtrack.
