I'd second this if you find yourself still having trouble. Rotate your wrists off the top of the hoods and drop your elbows a good bit; it will forced you to support yourself with your core and legs instead of resting your weight on your wrists and arms. It will lower your stance, like a few others have mentioned, and will help get more of your legs and glutes involved in pedaling.
Nice bike, btw.
