So I used to be an avid runner (though never much good), but after a lung infection I got out of the routine and now just don't have the passion to start all over.
I'd like to get back into good shape again -- and so thought of a course: karate, kickboxing, even rock-climbing to do it (though there's no wall in my area so this last one is out).
What's a good course to get fit, learn a new skill, and get into shape? I don't mind paying for a course, but online tutorials or podcasts work fine too (and given my schedule are even preferable).
Thanks!
