In some ways, kettlebells are astounding. Because of their utter simplicity, they become the most convenient form of exercise equipment possible, amazingly quick and useful. I can be sitting in my desk chair one moment, then on my feet picking up my 40 pound kettlebell the next. In another two seconds I am swinging the kettlebell and just 90 seconds (and 54 swings) later I am finished. I sit back down, huffing and puffing, energized and refreshed.
