Without gyms, people would resort to outdated fitness techniques such as swimming and pushing Model Ts up slight inclines.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 $25, you get a one-month women-only gym membership and an infrared sauna session or an ion-cleanse foot spa treatment at Go Fusion Fitness (up to a $94.98 value).

Go Fusion Fitness empowers female challengers with circuit training and health programs in its women-only workout quarters. Outfitted with nine easy-to-use hydraulic machines, including an ab machine, a leg-extension machine, and a shoulder press, this muscle lab invigorates ladies with 30-minute aerobic-circuit classes that solicit two muscle groups per station in order to harvest lean muscle tissue and boost metabolic rates. After each of the nine intervals, sneakered goddesses can reclaim steady breathing patterns and recite inspirational fortune-cookie wisdom during a designated recovery period that soothes tuckered limbs with restorative step exercises and cushioned platforms. Go Fusion also enlists treadmills, bikes, and ellipticals to work sweat glands during cardio training and targets torsos in its stretch and ab-exercise area. After the caloric bonfires, women can enjoy the fruits of their labour during a wellness and weight-loss evaluation that measures body fat, total lean tissue, and metabolic rate.

Go Fusion Fitness also indulges its members with a handful of spa services to flourish healthy habits and pamper active physiques. To jump start weight-loss plans, patrons can burn up to 600 calories perched inside an infrared sauna (a $29.99 value), a detoxifying treatment that can soothe sore muscles and invigorate immune systems. An ion-cleanse foot spa (a $34.99 value) purifies bodies through the tips of the toes, as the therapeutic sole bath helps eschew aches and pains. The family-friendly facility nurtures its stress-free ambience with free childcare from 9 a.m. to 11 a.m. and a strict ban on lie-detector tests.
