This weekend I was reading up on kettlebells and watching various kb routines on video. I thought, "Now this looks like an excellent way to do cardio" (I'm not doing any cardio at the moment) and thought that I might buy one. Then I saw the OUTRAGEOUS price - $90 for a 35 lb (16k) kettlebell! After I saw that I started thinking a little more rationally and began to wonder - is there anything you can do with a kettlebell that you can't do with a regular old dumbell? Is this just another fad? There are some very good kettlebell routines out there, but I have yet to see anything that you could not do using a dumbell. I'm I missing something?
