To a good tennis player, a racket is an extension of the arm, much like a spatula to a chef or a panicked starlet to King Kong. Learn to master your specialty with today's Groupon: for $12, you get a three-year subscription to Tennis magazine (a $24 value).

Gear reviews, tournament coverage, and the accouterments of life on and off the court leap from the pages of eight yearly issues of Tennis magazine. Readers race from their mailboxes to crack open bimonthly or special tournament issues, scouring for interviews with top pros, info on high-profile matchups, and critical analyses into which player is most likely to secretly be a golden retriever. Professional racket jockeys fill the pages with helpful tips for clinching doubles games, and lifestyle sections envelop readers in articles on health, fitness, and tennis-centric travel destinations. Special editions go in-depth on coverage of the U.S. Open and Wimbledon, and the annual equipment issue profiles the year's best new items and lets players find the perfect gear without casually asking if the racket in the pro shop mentioned them.
