Since the rise of the Internet, everyone has struggled to tear their now-useless phone books in half. Bulk up to succeed where others have failed with today’s Groupon: for $49, you get a 30-day membership, a health screen, unlimited tanning, and access to the kids' club at ActivEdge Fitness Club (a $174 value).

ActivEdge Fitness Club's experienced fitness gurus shepherd clients toward a tighter body with two stories worth of cardio and weight equipment, an ample number of group classes, a basketball court, and a 25-meter lap pool. Gain a better understanding of your overall well-being with a health screen, a preliminary fitness assessment that utilizes resistance and balance tests, optional body-fat measurements, and a trainer consultation to calculate an individualized plan for achieving physical goals. Then guests can put their plans into action by piloting more than 50 cardio machines in workout zones equipped with several flat-screen televisions. A variety of group classes, which include Kardio Kickboxing and the pool-based Nautical Noodles, confuse muscles much more effectively than performing a triathlon in zero gravity or telling sinews they were adopted. While adults enjoy postworkout tanning, the kids' club's mini basketball court lets active little ones exercise away pent-up energy and mimic legendary video-game character Michael Jordan.

ActivEdge also offers optional Apex Bodybugg monitoring armbands, which track burned calories on your Android or iPhone for easy goal tracking and digital bragging.
