It's mostly aerobic, with a little anaerobic thrown in, I guess, when I'm jostling for the ball and need to be strong.

I've always worked out inconsistently over the last few years, with the goal being to build my physique. I do want to do that, too. I have a pretty good weight routine down, it's just a matter of not slacking. I know less about running and that kind of fitness.

Last night I ran for 20 minutes and then biked for 20 minutes, and in a few days I'll increase that to 25 minutes running and 25 on the bike, then increase by five again after a few session/week or two. I've sometimes incorporated sprints into the running and biking, taking "breaks" (running/biking back at regular speed) before sprinting for 30 seconds or whatever.
