Tennis has long been considered the most versatile sport, requiring only overripe heirloom tomatoes and baseball bats to play.

Cardio Tennis fulfills the shameless dream inside all tennis pros and amateurs: furiously smashing hundreds of balls in a row while cranking powerful, grunt-inspiring music. Over the course of an hour, you and your cardio-mates will undergo the rigors of various fast-paced drills. While some technical tennis instruction may occur, the primary focus is placed on the aerobic movement and discovering the uninhibited side of tennis. The friendly instructors at Georgetown Prep will keep class-goers motivated throughout the hour, helping to burn calories, increase endurance, and improve ability to smash things.

The Georgetown Prep Tennis Club contains six meticulously-maintained clay courts and six U.S-Open-surfaced hard courts for your playing enjoyment. During the indoor season, the clay courts are covered with a climate-controlled air structure.
