Too shy, too broke, too busy, too lazy to hit the gym these days? With FitTV, a cable station that offers 20 hours of fitness and health programing every day, another excuse for not exercising doesn’t work. But you'll still have to get up off that couch.

"FitTV is currently the only network for fitness and keeping exercise and fitness programing fresh and accessible to everyone," Carole Tomko, president and general manager of FitTV, said in an interview.

Part of Discovery Communications Inc., the station offers the workout choices, ranging from Pilates and aerobics（有氧运动）to body sculpting, yoga, belly dancing and hip hop.

"I wanted FitTV to be a clear and inviting alternative to 'hitting the gym,'" Tomko said from her headquarters in Silver Springs, Maryland.

There are exotic locations. You may be in your living room, but decathlon champion Gilad Janklowicz, an aerobics instructor, is helping you develop you from the golden sands of Hawaii's Waikiki Beach.

In the "Namaste" yoga classes, bendy young women in sports bras and shorts execute their poses（摆姿势）as the scene behind them shifts from park to beach to sun-flooded studio.

FitTV also delivers lifestyle programing on nutrition and weight loss, and a video-on-demand service allows viewers to call up favorite shows at will.

Dr. Kenneth McCulloch, an associate professor of orthopedic surgery of New York University School of Medicine, said that in general, the concept is a great idea.

"It seems that they recognize that diet and exercise go hand in hand," McCulloch said. "The other major benefit is accessibility."

FitTV targets adults ages 25-54 and is available in 47 million homes nationwide, according to Tomko, who says the subscriber base has increased steadily since 2003.
