Boot camps are a quick way to get in shape for upcoming marathons or adrenaline-pumping prison escapes. Jump the fence with today's Groupon: for $69, you get four weeks of unlimited boot camp (a $150 value) at any of Boot Camp 512’s four locations listed to the right. The North Austin camp is held indoors.

At Boot Camp 512, the enemy is predictability. Each day, your trainers will throw down a fresh guerilla-ambush worth of challenges for your muscles and your brain, fueling constant gains and keeping you engaged. Over the course of the one-hour camps, you'll run, squat, lunge, slam out push-ups and chin-ups, juggle kettlebells, punch slabs of beef, and end with a live crocodile wrestle. At the beginning and end of each session, you’ll complete a personal-fitness assessment to help set goals and measure results.

Because healthy eating is integral to total-body fitness, Boot Camp 512 offers nutritional seminars to its campers. The on-staff nutritionist, Yvonne Graham, is a three-time Olympic bronze medalist. With a new nutritional outlook and a new workout routine, you can expect to drop 20 lbs and shave up to three inches off your midsection. At the end of your boot camp, you'll be so ripped and ripply, the ocean will want to surf you.

You must take all four weeks of boot camp consecutively.
