Tennis is like a political debate—there are heated back-and-forths, polite applause, and headband-wearing Swedes. Make a competitive racket with today's Groupon: for $35, you get three tennis lessons (a $75 value) from Move Your Feet Sports. Indoor classes are available at McClurg Court in Chicago and at Combe Tennis Center at Northwestern University in Evanston; outdoor classes are available at Northeastern Illinois University in Chicago.

Move Your Feet Sports' hour-long lessons teach all ages and abilities to serve and volley like professional bowlers who used to be tennis title holders. Classes for beginners, intermediate players, and advanced players ($25 each) are available at all three facilities. The staff of experienced instructors pump each hour-long lesson full of heart-pounding cardio moves, skill-building exercises, and techniques to crush competition like monster trucks crush hot-dog carts. Look under the Groupon tab on Move Your Feet Sports' registration page to see class options.

Improve your health and your half-volley as you work toward Wimbledon. Or get this Groupon for a tennis tenderfoot who holds a racket like a snake holds a medicine ball. You must reserve classes in advance online.
