Reading and exercise

I used to try to get a lot of reading done on the elliptical trainers in the gym. The idea is that I wanted to feed my mind, but I also wanted to trim down and get some exercise in. Unfortunately, it's hard to read one those things, especially when reading technical matters. It's also hard to concentrate on getting an intense workout when you're reading.

More recently, I've been watching some high-intensity cardio DVDs and participating in some bootcamp classes. You can't really read while doing those things; however, they do provide more intense workouts.

Argh. If only I could do both. I want to be an information sponge, but I also don't want to become a couch potato.
