Kettlebells are becoming a more and more popular type of training equipment. They're relatively inexpensive and can give you a full body strength and conditioning exercise. When done properly, Kettlebell training has proven to be more effective than a standard military regimen of pullups, sprints and long distance run. Kettlebell training is currently being incorporated into all types of training regiments especially amongst strength and conditioning coaches for athletes. You can improve your grip (grappling), explosiveness (striking), flexibility (both) and just overall cardiovascular training.
