Though canines love tennis for its bouncy yellow balls, humans appreciate the freedom to bark loudly with each swing and bury their favorite rackets all over the court. Become a tennis beast with today's Groupon: for $49, you get a six-week Baseline adult tennis program, plus a six-week membership, at Five Seasons Family Sports Club (a $99 value). This Groupon is valid at the Northbrook and Burr Ridge locations.

The six-week Baseline tennis program at Five Seasons Family Sports Club infuses beginners ages 18 and older with a passion for the game through energetic weekly lessons. Racket rockers learn from a team of experienced pros at both the Northbrook and Burr Ridge locations, each boasting climate-controlled indoor courts and adventurous outdoor courts completely at the mercy of the climate. Students harness basic footwork, forehand, backhand, and behind-the-back no-look slam dunks in a group setting. Social events let fellow net apprentices compare notes throughout the course, including a welcome reception, a member-appreciation party, and a graduation mixer. Any student not born with rackets for arms—or who simply doesn't own one—can borrow one from the club. Classes are generally held Monday through Thursday and on Saturday, with morning, afternoon, and evening sessions available; students should call the club of their choice for complete scheduling information and sweatband fashion tips.

During the six-week Baseline tennis program, the facilities at the Five Seasons Family Sports Club welcome all court conquerors. When not practicing the game where love counts for nothing and winning means everything, patrons can hit the basketball courts, take a dip in the pool or whirlpool, sweat it out in the sauna, and build endurance on more than 100 cardio and strength machines.
