Although body-exchange programs mean no one ever has to stay in one meat suit for long, returning yours in bad condition means you forfeit your deposit. Keep your constitution in returnable condition with today's Groupon: for $30, you get 30 visits to The Sporting Club in San Diego or La Jolla Sports Club in La Jolla (a $450 value). This Groupon is valid for 30 individual day-passes good at either facility—not a month's membership—so you never waste a day you paid for.

The Sporting Club and La Jolla Sports Club are well-endowed workout warehouses with group exercise studios, a convoy of cardio machines, muscle-molding weight equipment, a roster of experienced staff members, and luxurious locker rooms (the San Diego club has a steam room, Jacuzzi, sauna, and towel service). The San Diego location's classes can help bodies reach their chiseled potential with variety of Pilates and strength-training offerings. Slam dunk stuffed animals on basketball courts, befriend lonely racquets on two outdoor tennis courts, bob for apples in a swimming pool, or tame other unruly muscles with the club's numerous fitness programs.

The La Jolla class schedule makes bodies beg for a break during numerous dance and cardio-blasting courses. Fitness programs run the gamut of body-beautifying bounty, from spinning to yoga. On-site childcare is available at both clubs for an additional fee and promise to invite a staff member to your child's next birthday party.
