kettlebells?

inkedshears

i do a kettlebell workout i got from self magazine. i really like it but it says im burning like 300 cal in 20 min.. am i actually burning that much? im confused.
its a good workout eitherway but i want to be able to log it in my exercises.

If it's a good intense routine it's entirely possible. 900 cal/hour doesn't sound unreasonable. I know when I do kettlebell workouts, it smokes me.
