A tall person may look impressive with clothes on, but the taller you are, the harder it is to look 'big' with your shirt off. There's a good reason why most BB champions are below 6ft.
This. It's all great being 6' 3", but when I am lean, I look like I am on the Bataan Death March. Somedays I think it might be easier to grow taller than to put on quality size.
