Kettlebell - Exercise Log

Hi,

Does anyone have any idea what sort of exercises might be equivalent to a 15-20 minute kettlebell workout? I would like to be able to log the little exercising that I actually do, but kettlebells are not cool enough to make the database list!

It's an anaerobic workout and I use a 36 pound bell, if that's at all helpful. I can't think of anything comparable, but I'm no athlete either so if anyone could provide some input, that would rule.

Thanks!
