Kettlebells can be a great workout, but the risk of injury is high if you're new to it and not doing the movements with proper form. I would recommend going to a class with a trained instructor at least a few times until you're sure you are doing the movements correctly, and then perhaps you can move on to doing the workouts on your own at home.
Hope that helps,
