I would like to do a trainer ride when I get home tonight, but I'm not a good inside afternoon exerciser. The trainer is useful, but absolute torture. I've only used it about 4 times since I bought it several years ago. The trainer allows me to turn my road bike or tri bike into a stationary bike. Cool concept. High boredom factor. Maybe really good tv will distract me. Hopefully. One of my favorite cooking shows is on tonight, so maybe that will do the trick.
