Exercise would be doubly efficient if people could split into two halves and have both body sections burn calories simultaneously on a tandem bike. Today's Groupon makes the most of feasible workouts. For $39, non-members get 14 visits to Renaissance ClubSport Aliso Viejo, a $350 value ($25 per day). All 14 sessions must be completed within 60 days of your Groupon purchase.

The luxurious, 12,000-square-foot Renaissance ClubSport facility is large enough to stump 7th-grade geometry students and solidify "ClubSport" as a successful punchline to a yo mamma joke. It houses two pools, three squash courts, heaps of the latest exercise equipment, piles of uncut iron, and more. With today's deal, you get access to the whole Renaissance ClubSport kit and caboodle, including any of the 110+ group fitness classes that take place each week. Learn to do the sideways-sauntering spatangoid and downward-facing dobsonfly in a yoga class, then soak sore muscles in the luxurious locker-room whirlpool, or sweat out lingering stress in the sauna. Check out information on all the amenities here. While private instruction (such as private swimming lessons and personal training) is not included in today's deal, Groupies can pay a non-member fee for one-on-one lessons and services.

Whether it's delinquent core muscles that need a talking to, sports-withdrawal jitters that need calming, or former reverse mermaids in need of a daily swim, the expansive facilities are the means to any end. For those not yet tall enough to ride the elliptical, childcare is available for up to three hours ($8 per kid, up to two kiddos per exercising adult). With spring spreading as quickly as a contagious yawn, now is the ideal time to get in shape for this season's fashionably risqué bloomers.

Valid for non-members only. Must be 21 or older.

Reviews

Though many online reviews are for the room and board side of Renaissance's gym/hotel hybrid, fitness fans on Yelp give the workout facilities 4.5 stars, while six Citysearchers give four.

• By far the nicest gym there is. Service is awesome. Trainers are top notch. – barbierim, Citysearch
• You get everything you want. The work out area is first rate. In addition to the latest equipment, it has handball and beautiful hardwood basketball courts to get your game on. – Lisa Z., Yelp
