Without gyms, people would resort to outdated fitness techniques such as swimming and pushing Model Ts up slight inclines.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 $49, you get a one-month unlimited membership (an $88 value) and a 30-minute Swedish massage (a $50 value) at Tri-City Wellness Center in Carlsbad (a $138 total value).

Stretching across 58,000 square feet of floor space, Tri-City Wellness Center boosts bodily beings through its standard fitness, wellness programs and group exercise classes held seven days a week. An all-access pass grants entry into the aqueous arms of two saline-treated indoor pools, separate men and women's jacuzzis, and wet saunas to replenish thirsty gills. Follow swims with a frolic through Tri-City Wellness's cardiovascular-training center, or sedate spirits in the body/mind studio while looking onto a serpentine wall and listening to the hushed trickle of cool water. The center accommodates all fitness interests, from cycling and free weights to wellness programs and physical therapy. Once properly detoxified, slip into the full-service locker rooms, where complimentary towel service, hair dryers, and toiletries await, along with digital lockers with slipped-in love notes from pampered biceps.

Owned by the Tri-City Medical Center, the wellness outpost takes an integrated approach to physical fitness and biological health. Once muscles are tuned up tighter than a pop-rock piano, relax them with a renewing treatment in one of three oversize wellness spa rooms while the vocal stylings of Falco run through your head. As part of each one-month membership, guests may bask in a circulatory-enhancing Swedish-massage treatment that can improve circulation, decrease stress, and enhance flexibility. Tri-City Medical Center also offers child care service for an additional cost.
