The muscle-up is a rare beast – an upper-body exercise that requires both pulling and pushing power and phenomenal core strength to boot.
Those unfamiliar with the move say it's just a pull-up combined with a dip, but a muscle-up is much more than that. It's an unparalleled assault to the upper body, and you have to be strong just to do one.
They're both assets to my training programs. Indeed, I've used kettlebells for years with success. And Pavel? He's a good guy. I definitely consider him a friend and a juggernaut in the strength and conditioning community.
