I pretty much gave up watching TV in order to be able to work out every night, work full time, & go to college. I don't miss it. I do Tivo some shows and watch them on the weekend. Working out makes me feel so so SO SO SO SO SO SOOOOOOOOOOOOOOOOOOOOOOOOOOOO much better. I think the trick for me was to do it often enough that it became habit. It's no longer optional for me.
