Without gyms, people would resort to outdated fitness techniques such as swimming and pushing Model Ts up slight inclines.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 $35, you get a one-month membership to the Dimond Athletic Club on Dimond Boulevard (a $70 value).

Endless rows of machines and plentiful amenities make this recently updated, 40,000-square-foot gym a luxurious emporium of healthy living. Dimond Athletic Center offers a variety of equipment for total-body fitness, allowing members to break a sweat on Precor treadmills, stationary bicycles, free weights, and low-impact ellipticals, or firm up out-of-shape thumbs on the computerized, user-friendly Life Fitness machines.

Group classes motivate members to partake in regular workouts with a variety of styles, including the wildly popular CrossFit, which is taught by a certified trainer and incorporates all major muscle groups.

Members can take full advantage of Dimond's updated facility during their month-long toning test drive by swimming or puppy paddling around the gym's lap and small pools, as well as relaxing in the hot tubs, hot-sauce tubs, saunas, and steam rooms. Those suffering from sneaker allergies can swap sock shields and get an unconventional workout at the gym's ice rink or bowling alley.
