One of my very good friends and personal trainer Adam Cronin doing a crazy kettlebell "Kettle-beach" workout. Now, don't try this at home, he's the master, he's been doing this for 10+ years and has literally written the book on kettlebell training. Yes, you always start out with the basics, but this shows a level of mastery that I don't know if you've ever seen before with kettlebell workouts.
Kettlebell workouts are great for all aspects of exercise and rehabilitation. This just shows where you can go with it once you've mastered it. And yes... he trains the trainers. So if there's a kettlebell class in your gym, it's likely he trained your trainer or trained the person that trained them. Enjoy
