Marcelo Garcia is a phenomenal grappler. And so is BJ Penn. And Dave Camarillo. And Demian Maia. And John Danaher. And Renzo Gracie (and pretty much every Gracie for the matter). We look up these grapplers, and we seek to emulate their often god-like abilities, but there is one thing that all of these individuals have in common that the vast majority of us normal guys and girls don't: they have a lot of time to train.
