Tennis is called a mostly mental game, due to the tactical depth of play and the ubiquitous use of telepathy to blind line judges. Expand tennis knowledge with today's Groupon to Peachtree City Tennis Center. Choose between the following options:

• For $36, you get a pass good for seven drill sessions (up to a $72 value). The pass can be used for any combination of two-hour round-robin sessions (a $7 value each), fast-feed sessions (a $12 value each), and cardio-tennis sessions (a $12 value each).
• For $42, you get enrollment in a seven-week tennis clinic, which meets for one hour each week (an $84 value). Peachtree City offers lessons for junior beginners, junior intermediates, adult beginners, and adult intermediates.

Between the lines of Peachtree City Tennis Center's 24 courts, expert instructors lead aspiring athletes through structured lessons and drills. Commit groundstroke adjustments to muscle memory with a fast-feed drill session, reduce both unforced errors and calories in a cardio-tennis session, or poach your opponent's weak returns and unguarded Gatorades while tending the net during a two-hour round-robin doubles session.

A seven-week tennis clinic caters to those seeking more instruction time, beginning with a brief evaluation session in which a staff pro places athletes in classes with players of their own ability and similar thickness of headband. Beginner clinics teach adults and juniors how to strike the ball cleanly and move their feet to set up shots, spurring improvement of hand-eye coordination through fun games and drills. Novice net clearers thrive in intermediate sessions, where they can build form through drills and work out in cooperative point play as instructors analyze areas for improvement and knit each pupil an eye-catching scarf out of tennis-ball fuzz.
