Since the rise of the Internet, people have struggled to tear their now-useless phone books in half. Bulk up to succeed where other have failed with today’s Groupon: for $99, you get four weeks of boot camp sessions at Omaha Adventure Boot Camp (a $199 value), taking place at Walnut Creek Lake and Recreation Area in Papillion, and at Elmwood Park, Standing Bear Lake, and Zorinsky Lake Park in Omaha.

At Omaha Fitness Adventure Boot Camp, coach Corey Cain and his experienced staff help shapeshifters of all abilities whittle down with hour-long, outdoor fitness sessions. The four-week camp begins with a review of medical history and a pre-camp physical assessment, in which the staff discreetly records your weight and measurements for comparison at the end of the camp. Using the outdoors as the gym space, newly knighted fitness warriors in groups of no more than 40 will swap fruit smoothie recipes with local wildlife as they run trails, roll tractor tires, and engage in other exercises designed to help build strength and endurance while reducing fat. Campers will also learn tips for maintaining a healthy post-camp lifestyle. After the camp, original body measurements emerge from their holding cell for comparison with the new ones, both of which immediately realize they have nothing in common. Classes are held at various locations and times, so check the calendar to chart your fitness course.
