My friend is really into parkour, i've tried it a bit and it's really fun.  what kind of workouts would help me get in shape for that?

I don't know if there's any specific training, but i would think circuit training would be good preparation.

I don't know about the training, but my friend showed me a video on youtube of parkour, it was amazing!  they must be so fit.

Running would definitely be a part of it, and some plyometric for all the jumping.

I'd love to love try that, but i think i'm a wee bit too old!
