MARINA DEL REY, Calif. (KABC) --A fitness class in Marina del Rey takes playing tennis to a new level. The number one rule is you keep your feet moving the entire time.
The ball used in cardio tennis is not your standard tennis ball. It's got good bounce, but a bit more weight, which can help the novice get it over the net.
Cardio tennis is offered at the Marina del Rey Ritz Carlton. They also have locations in the Valley and Pasadena as well.
