Without gyms, people would resort to outdated fitness techniques such as swimming and pushing Model Ts up slight inclines. Celebrate contemporary fitness with today's Groupon: for $39, you get a one-month membership with unlimited group classes at Hampton Hill Athletic Club (an $80 value).

Hampton Hill is a privately owned and operated athletic club with fitness equipment, classes, spa services, and a high degree of commitment to its members’ satisfaction. The multi-leveled fitness oasis has three main gyms with weight machines, free weights, stationary bikes, treadmills, and elliptical machines, making each workout as varied as the Eskimo word for 'snow.' The abundant class offerings run the gamut of fitness, from yoga, Pilates, spin, abs, all the way back to total-body cardio. The gym’s Biggest Loser Challenge invites members with serious weight goals to join their peers and shed pounds in a positive, supportive environment—as many as 80 people have participated at a time, with winners dropping as much as 60–70 pounds over the course of the six-week program.

Hampton Hill's amenities aren't limited to muscle maintenance—their on-site day spa and juice bar provide subtle a luxurious touch. Patrons with children will appreciate the on-site nursery at Hampton Hill, which enables fitness addicts by adding flexibility to childrearing schedules. The floor-to-ceiling windows lining the front of the club let the sun shine in, though on cloudy days the healthy glow of fit faces and fat-burning muscles will suffice.
