Like early cavemen, humans exercise best in groups to ensure saber-toothed stationary bikes don't pick off the stragglers. Bulk up pack mentalities with today's Groupon: for $29, you get one month of unlimited outdoor boot-camp sessions (a $99 value) from Orange Shoe Personal Fitness. This Groupon is valid at their Fitchburg, Middleton, and Madison locations.

The certified trainers at Orange Shoe Personal Fitness coerce strength and agility out of unmolded clients through lively outdoor boot-camp sessions. Each 45-55 minute body barrage spurs groups on with cardio training, strength training, and calisthenics exercises that tone core muscles and ready bodies to audition for Breakin' 3: Breakin' with a Vengeance. Supportive coaches inspire campers to test their personal limits and offer individual guidance to make sure every participant is having fun and benefitting from the experience. Instructors use local natural environments to enhance the creative workout as participants take advantage of the warm summer months and encourage lazy trees to get back into sapling shape.
