Two-time U.S. Open champion Tracy Austin likes knowing she doesn't need to scramble to find tennis partners Tuesday, Thursday and Saturday mornings.

"I don't have to call people and make plans; I know that those are my times for me," said Austin, 43.

Instead, she joins a group of others participating in Cardio Tennis, hour-long clinics designed to help improve a player's cardio and tennis levels.

She'll be in Hawai'i to host and promote the clinics on Tuesday and Wednesday on Maui and O'ahu.

"The emphasis is more on the cardio than the tennis, and it can be for any level of tennis player," she said. "If you can move and you can run, you're ready. If you desire to have a great workout, you're ready for Cardio Tennis."

She feels better "all the way around" when she completes a good workout, both physically and mentally, and wants to share the benefits of the clinic with other tennis players.

Cardio Tennis is not only for experienced tennis players like Austin.

"This is a way for someone to get back into the game and enjoy it, and for someone who has never tried it before to not be intimidated," she said.

She enjoys the constant movement the drills provided.

"As soon as a point is over, a pro is feeding a ball and the next point starts," she said. "It's constant; as soon as the point is over, you look up and the next point has already started."
