Watching tennis can work up quite a sweat, with its constant head and neck swivels, but it doesn’t compare to the workout of a real, live on-the-court experience. Develop an envious swinging technique and firm figure with today's Groupon: for $29, you get five one-hour tennis clinics and a two-month membership to the gym at Tucson Racquet & Fitness Club (a $363 value), located in the Foothills. Spawning via cellular mitosis from a single neon-green tennis ball in 1967, Tucson Racquet & Fitness Club is a 20-acre, 24/7 facility that boasts 33 outdoor tennis courts with lights, 11 indoor racquetball and handball courts, two 75-foot heated pools, basketball and volleyball courts, and a complete fitness center.

Tucson Racquet & Fitness Club's clinic will meet every Wednesday at 6:30 p.m. for five straight weeks (a $90 value). Lessons are taught by expert instructors and consist of intense hitting drills, strategy, footwork, girthy grunts, and supervised play. With a 4:1 student-instructor ratio, you'll always have watchful eyes to monitor your progress and make sure you're not sneaking in corked racquets. Regardless of one's swing swagger, all players are placed into compatible groups based on ability and the number of rings on their torso stump. By clinic's end, rookie racqueteers will transform into veteran volley maestros that propel slingshot swings with a Bruce Lee accuracy (Lee was actually a much better tennis player than he was a martial artist).

Along with tennis lessons, you can also forge fortitudinous forearms for fortified forehands with a two-month gym membership (a $273 value, including the $125 initiation fee). Facilities include a fully equipped weight room, cardio center, a bevy of sports courts, two Jacuzzis, a steam room and sauna room, and access to all fitness classes. Check out the schedule, which offers more than 100 classes such as yoga, Pilates, and aerobics each week.
