Do you play tennis for exercise, or do you exercise to play better tennis? Either answer is perfect for HVTC’s cardio tennis program. Cardio tennis is a low-impact drill session designed to get the heart rate up and the feet moving. It’s a one-hour class with lots of movement and occasional breaks. The two sessions are Monday 1:30–2:30pm and Thursday 2–3pm, and signup is weekly. The cost is $18 for members, $20 for nonmembers.
