If your not doing so already, do more heavy Barbell Rows in your workout along with Squats and Cleans. When I was in HS I had 14 inch ish arms and had a 2 rep max of 225 at 5'11" so I don't think it's that off. But also if your 5'9" and 215, how much of that is fat. AND while we are on the topic, I hope you're eating properly.
