Unlike the instant gratification of government-funded genetic engineering, manually achieving a slim and toned physique can be a lonely, bumpy road. Give your willpower some company with today's Groupon: for $39, you get a four-week boot-camp program, including unlimited classes, at Maximum Fitness in Mount Washington (a $299 value). Most Groupon holders will begin their program at the start of a new four-week session. Click here to view the schedule.

Maximum Fitness scoffs at the monotony of traditional gyms and provides ever-changing, camaraderie-driven boot camp to keep trainees engaged. The four-week boot-camp program kicks off with an orientation, generally held the Saturday before the start of a four-week session. Trainees then attend as many 45-minute boot-camp sessions as they please, joining forces with 10–40 supportive peers during each gathering. Classes aim to torch calories, flattening façades before beefing them up with lean, tone muscles. Maximum Fitness perpetuates health with a class trip to a local grocery store that teaches students how to select healthy food, how to military-press a bagboy, and how to adhere to their included at-home nutrition guide.
