I have noticed the same thing about television, in particular with certain programs motivating me to go exercise.
I also noticed, however, that I had to be careful about when I watched TV, because the effect was so strong. Watching The Biggest Loser or youtube Crossfit videos (highly recommended) would get me so excited to workout that it started affecting my bedtime--namely that I wouldn't be able to go to sleep because I was so excited.
I found that I need to watch those programs at least three hours prior to my bedtime in order to be able to fall asleep. The end result is that I now only watch them on weekends or my lunch break.
As luck would have it, I've also drastically cut down my caffeine intake recently, with the curious side-effect of giving me insomnia. I'm planning on taking up after-midnight jogging.

This is the public group instrumental rationality diary for the week of May 21st. It's a place to record and chat about it if you have done, or are actively doing, things like:
Or anything else interesting which you want to share, so that other people can think about it, and perhaps be inspired to take action themselves. Try to include enough details so that everyone can use each other's experiences to learn about what tends to work out, and what doesn't tend to work out.
Thanks to everyone who contributes!
