This article for Again Faster focuses on how to become an elite athlete. But really, these are all goals for every one who CrossFits to strive toward.
Almost all of this is common sense, really. Clean diet, rest days, decrease stress, sleep enough, etc. Dion has blogged in the past about virtuosity and getting outside of your comfort level before, too.
Virtuosity means making sure you are doing every rep correctly with the right form. This will eventually lead you to better performance. Don’t try to skip virtuosity in your WODs – it makes a huge difference if you are doing every movement correctly! This may mean you have to decrease your weight. THAT IS OK! Unsure if you are not correct on a particular movement? Don’t wait to be told, just ask your trainer – that is what they are there for. They will guide you to perfect form.
Stepping outside of your comfort level quite simply is trying to doing something you couldn’t do before and continuing to work at it until you can. For many beginners, that can be as simple as jumping onto a 12 inch box vs. stepping up. Or it can mean getting your first couple double unders without a break. For more advanced, it can be the holy grail (to many) of CrossFit movements – the muscle up. Or reaching an elusive PR on an Olympic Lift. The point is, if you don’t step outside your comfort zone, you won’t grow!
