Have you noticed a new funny/medieval looking dumbbell type of thing at the gym that looks like fun. Sounds like it could be Kettlebells...

What is a Kettlebell? Basically a Kettlebell is a rather old fashioned looking training tool that looks like a cannonball with a handle attached to it. They are designed to be swung (with a controlled motion of course), rather than lifted giving a more dynamic workout that is great for building functional strength. Kettlebelling (as some like to call it) is a great supplement to your current dumbbell/barbell lifting routine. You'll instantly feel like smashing something with it, but I recommend against it, those babies are meant for training only - It's fun and definitely adds variety to your workout.

I would recommend getting a book, dvd or finding an instructor rather than going at it alone. Especially since the multi planar movement, while great for muscle development, can lead to injuries if not done properly. A fun new group class (Kettlebells swung to music) led by fitness pro Keli Roberts, Total Body KB Blast, will be launched soon as well, so look for that as well as other Kettlebell classes at your local gym now. Really interested? You can always buy your own Kettlebell from Amazon.com
