Barelynangel, kbells have grown in popularity in the past few years here in America, but they've been around and been used in Russia for some time. The reason they're not more popular is because they're really really hard. There are dozens of different exercises you can perform with a kbell, but the most basic is the two handed swing. Is that what you're asking about? If so, then your back will be fine, as long as you do it correctly. The biggest problem people have is they want to use their arms, their upper back, during the movement. Your arms are loose, and are only moved by the momentum you generate with your lower body. A proper swing is not a squat motion. Your knees are unlocked, core tense, and you let the kbell's momentum pull you down, before driving back out as hard and fast as you can, squeezing your glutes as hard as you can. You're not slowing the weight down, you're letting it complete its swing, like a pendulum. And when it comes up, you're not pulling it up with your arms. It's actually a very natural movement for the body. I've done swings with kbells up to 130lbs, and never had any pain issues.
