Yes, you can work every muscle with a kettlebell. Unfortunately, it's a common misconception that kettlebells are just for swings. The kettlebell swing is a very popular exercise as there are no other tools out there that allow you to swing a weight explosively. This doesn't mean the kettlebell is only good for swings, on the contrary, the kettlebell allows you to do every exercise that you can do with any other piece of equipment plus a whole lot more.
