There is a new fitness craze called Kettlebell. What is a Kettlebell you ask? 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. Actually it's how Geri Halliwell got in shape. 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. You can always buy your own Kettlebell from Amazon or see if one of these Houston area kettlebell clubs will "workout"!
