One of the best training tools for supreme fitness and physical conditioning is not new. In fact it's centuries old. Kettlebells came into being sometime during the 17th century in Eastern Europe. Popularized by strongmen during Tsarist Russia, kettlebells have survived centuries for one reason and one reason only: they work. Kettlebell training can deliver not only a great strength workout, but also a vigorous cardiovascular exercise as well.
Used by elite law enforcement all over the world, kettlebell training is famous for total body fitness, especially your core muscles. There are really no other exercises, and certainly no machines that deliver the kind of core conditioning that kettlebells do. Proper technique is the key to success with kettlebells however. If you think you can just come in and start flinging them around and walk out with a hard body in twenty minutes, then don't even bother. Kettlebells need to be learned, and then trained with judiciously to achieve best results. It's not unusual to people to not only gain a great deal of specific strength and gain muscle mass while at the same time paring down their body fat and actually losing weight at the same time!
Some people wonder why you can get the same effects using dumbbells. Fair question, I mean, kettlebells themselves aren't dirt cheap. (They're not overly expensive either!) Probably the best way to answer that one is to say that by virtue of their unique design kettlebells offer the added benefit of momentum in your exercise routine. This sounds like no big deal, until you understand that everything in life has momentum, and kettlebells are built to exercise that. Bending over to pick up that spilled load of groceries, picking up children, (especially squirming ones!) and almost an innumerable amount of daily chores that task us in a dynamic way. Kettlebells, by virtue of the use of momentum, train those muscles that might miss out on this with only the use of a weight machine.
Kettlebell routines routinely take less time and burn far more fat and calories than more conventional methods. A twenty minute kettlebells workout performed three times week can bring a wealth of results very fast. You should start with some of the more basic exercises, like the swings. You'll eventually graduate to some of the more complex exercises, like the cleans and jerks, Turkish get-ups and more.
Make sure to get some instruction and work with either a teacher or partner at first to learn proper technique and avoid injuries.
Kettlebell training can bring you some great results in your total body conditioning efforts. Make sure you use them wisely and often!
