If anyone wants to get a kettlebell before it comes out to try it out I recommend getting this from Wal Mart:
Danskin Now 10lb Kettlebell (they also have it in 15 lb if you are more advanced, but I recommend going down a little in weight with the kettlebell -- if you are lifting 15 lb weights, the 10 lb should be fine)
It's awesome. It comes with a DVD that has 3 10 minute workouts on it, and it breaks down all the typical kettlebell moves. You won't believe how much it gets your heart rate up and how sore you are the next day. I swear by kettlebells.
