I love fit tv! especiall all stars workout where you can do a different workout everyday. sharon manns is my second favorite. and I love carribean workouts when then do yoga
They have it on satelite television, not sure about cable but it saves you money on dvds/videos and it's fun to flick to it during commercials to get a workout in. they also have good shows like ship in and shape up, and living fresh, and house calls where they talk about good nutrition and stuff and how they help people lose weight. it gives you great advice.
anyway check your guide to see if you have it. if you have direct TV. it's on channel 368
