Being in shape makes seemingly impossible tasks much more plausible, such as running a marathon or running a marathon to the moon. Take a giant leap toward achieving your goals with today’s Groupon: for $69, you get four weeks of unlimited fitness boot-camp sessions at Camp Gladiator (a $160 value). This Groupon is valid at all San Antonio-area camp locations.

An intensive four-week exercise regimen crafted by certified personal trainer Ally Davidson guarantees speedy results and sweat-addled brows for campers across the fitness spectrum. Ally’s local boot-camp staff sends muscles on a brisk march toward a firmer condition six days a week, helming total-body workouts that include interval training, plyometrics, and an abs-twisting assortment of timed strength and agility drills. The staff regularly switches up workout regimens to ensure that muscles don't become as bored as nihilists in a bounce house. Aware that not all recruits have the same motives for joining their flab-busting brigade, trainers customize their workouts to squeeze the best results from bodies of all ages and fitness abilities. The camp schedule varies based on location, with four early-morning camps to awaken muscles stuck on snooze and a pair of evening sessions to end the day on a note of high endorphins.

Trainers request that campers arrive 10 minutes early and bring a mat, towel, dumbbells, and water to each session. Participants must sign a waiver and register before they are admitted.
