Flipping a tire end over end is both a common boot-camp exercise and a gross misunderstanding of what the wheel was meant to do. Rethink conventions with this Groupon.

$29 for Four Weeks of Unlimited Boot-Camp Sessions and a Nutrition Seminar ($234 Value)

Each 40- to 45-minute boot camp begins with a warm-up as students stretch and limber up cold muscles on foam rollers. Workouts move on to an interval-based regimen of strength and cardio circuits. Participants hoist free weights, swing kettlebells, stretch resistance bands, heave heavy ropes, and perform circus tricks atop medicine balls. Trainers make modifications to the exercises to accommodate guests of any fitness level, and small classes of only 10–15 students give ample time for meeting personally with the trainer before and after sessions.

Muvement

Muvement is as much a gym as it is a physical-fitness lab. Certified strength and conditioning specialist Michael Houle and Jill Houle, who holds a BS in nutritional science, team up to invest clients with practical workout regimens and an intimate knowledge of how the body works on a physiological level.

Before new clients lift their first weight at the studio, a personal trainer consults with them about their exercise and health history and runs physical assessments and lab tests to identify potential obstacles related to the immune, digestive, hormonal, and detoxification systems. Next, Jill draws on her background as a professional nutritionist to recommend a diet suited to the client’s unique metabolism, and explains how the body breaks down calories and nutrients. Even their fitness regimens take a holistic approach. Whether in group or personal-training sessions, functional movements using resistance bands, TRX suspension, and kettlebells incorporate multiple muscle groups and joints into each exercise, building a physique more balanced than two eggs riding a seesaw during the spring equinox.
