IDK if mine counts; I've never been clear on the exact line between cardio and strength training, because most of my cardio comes in HOLY GOD MAKE IT STOP style, with resultant big bulging muscles. I mean, when I'm on my highest gear biking uphill, it doesn't feel much different from one of those leg-pushing machines with a LOT of weight on it, you know? (Except then I get to crest the hill and coast down the other side--silly machines don't let you do that!)


Anyway. If any of you know the line better than I do, I'd love to hear a clear explanation of the difference between that and the leg machine thing. (Is it just "duration"?)
