Kettlebells

I'm learning about Kettlebells.  I don't do the Russian variety... because I'm a wimp... light weight.  This guy shows 17 different exercises using kettlebells - I can't wait to try a few.  I do the "swing" - both hands on and in between my legs.  I actually use a dumbbell... because I don't own any kettlebells as of yet.

Today I did 100 swings.  I read somewhere that doing swings burns 20 calories per minute.  Thus - doing 20 minutes of swings... LOTS of calories.  Ü  (400... in case you were reaching for your calculator).
