thats a great picture, thanks for posting it! it just goes to show you how much leaner muscle is than fat, and why its so hard to lose pounds when you're gaining muscle mass...even if your losing inches!
one of the most motivating things i have ever seen was along the same lines. while observing a cardiac bypass case i got to see the inside of a blood vessel that was clogged with plaque build up. every time i want a cheeseburger i try to imagine all that plaque and remind myself that i want to be healthy!
