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 $65, you get a four-week fitness boot camp at Transform FX Fitness Bootcamp in Concord (a $247 value).

The fruit of trainer Anna Dornier's struggle with weight gain, Transform FX Fitness Bootcamp distills the lessons she learned about exercise and nutrition into an intense program designed to safely and efficiently burn fat while increasing strength and energy. The thrice-weekly, 45-minute workouts emphasize total-body fitness and focus on strength, flexibility, and conditioning to create a bodily environment as inhospitable to flab as most fine-dining restaurants are to hungry gremlins.

Each session is different, keeping minds engaged and bodies on their toes, maximizing each workout's effectiveness and ensuring that there isn’t a dull or predictable day. Weekly weigh-ins and a one-month body-composition tracker let bootcampees see how much fat they've burned and muscle they've put on over the course of the camp. Access to an online community of fellow workers-out is included, allowing tip swapping, moral support, and the sharing of adorable pictures of physically fit cats. The boot camp is a continuous four-week program, click here to view the schedule.

Reviews

Twelve Yelpers give Transform FX Fitness Bootcamp, formerly ATD Fitness Bootcamp, a perfect five-star average:

• I highly recommend using ATD fitness. Now, working out isnt a chore... I get results and I'm done with my workout in 45 minutes (vs 1-2 hour plus at the gym). – Vicky T., 6/25/10
• It's low pressure, and you can be at any fitness level to participate. Even as a beginner, I didn't feel overly pressured. – Trae D., 10/4/10
