Take the kettlebells and use them for paper weights. They are also good for keep doors open when needing extra ventilation while doing real work. Then inbox me and I will give you my address or pay pal account. Then you can send me 20 bucks and thank me for saving you from fad workouts and the latest craze.
Kettle bells have been around for centuries. People are using them now, suddenly, because they are usually shiny and color coded, like bosu balls. They are a lump of dense mass like other weights and just slightly more comfortable than a dumbell for doing SOME movements. They are a tool. You can take a hammer and build a house or bang yourself on the head with it. Most people doing and teaching kettlebells are ignorant and the teachers are cashing in on the craze and trying to make them look special. As I say, what good is it if you learn this crap, or some dance dvd, or some other dvd, but don't learn how to properly squat?
Do your normal workout, learn how to do your basic core complex movements of deadlifts, squats, presses, rows, pull ups, etc., and learn about proper support and protection of the lower lumbar, all the while studying about nutritional manipulation. Then come back and do the kettle bells when you have time to actually learn about what you're doing. Then you'll realize you probably don't need them! Then you can send me another 20 on principle.
