Like tug-of-war tournaments and harmonized singing telegrams, workouts are more effective when done with a group. Join a fitness community with this Groupon: for $39, you get unlimited outdoor boot-camp sessions through September 30 from MetaBody Yoga & Fitness Pass (a $300 value). This Groupon is valid at the locations in Thornhill, and on Chatsworth Drive, Queen’s Quay, and Dundas Street in Toronto. Click here for a schedule of available class times.

The inspiring trainers of MetaBody lead troops of female workouteers in results-oriented boot-camp sessions several times weekly. Sweat sessions utilize a variety of exercises and disciplines to produce full-body results in a supportive environment, ideal for beginners and hard-core core hardeners alike. During any class, motivational instructors will use humanity's instinctual distrust of routine to their advantage. Muscles are kept guessing with new and challenging moves as well as the occasional heart-pumping round of “What’s My Line.” In addition to the boot-camp classes, students receive a success guide to help prepare for imminent pound loss, as well as a nutrition guide.
