It's a nationwide program that select tennis centers adopt. It involves drills and cardio work to music. I go to a class on mondays. Last night I discovered that the ex-pro played at Wimbledon!!!!! Amazing. She faced Pam Shreiber (#5) in 1978 and got creamed in the 1st round because of her nerves. Interestingly, that is the year I took tennis in high school. Part of the course we were taught which were the top players. I could never remember and it turned out Pam was one of them.
