These guys have some great functional strength. I wish I had the space for some of this stuff. The stone donut looks like it would be great for neck strength. [ame="https://www.youtube.com/watch?v=qWQCrYk3Rjc"]Indian Clubs | TRAINING at SURIA AKHARA - YouTube[/ame]
Love these videos, I've always been a massive fan of this style of training. The grip strength needed at the 12:00 mark with the climbing the rope is just absurd.
I would be impressed if it was one of the skinnier guy. That guy climbing with arms only ain't exactly lean!
