Yep, and they do a workout immediately before filming a scene so that they have what bodybuilders refer to as 'the pump' or the bulky, swollen and/or vasculated vein look. Unrepresentative of the normal human body.

In fact, muscles like that do happen naturally, but usually only for a short amount of time and usually only from the world's top athletes. For example Jessica Ennis one of our sporting greats with cobblestones for abdominals. No one stays in that shape for very long and it's not certain to be good for your health to do that.

On top of that, due to the varied gene pool, people in peak physical fitness can take on all sorts of shapes and sizes.

I could stare at Jessica Ennis' gams all day long from a thousand different angles!

Why isn't Jessica Ennis in the tags. She's a gold medal winner in an event that's actually seriously tough...it's not like the 500 different swimming events that you can compete in and get medals galore! She's fucking awesome!

Also not a Harry Potter fan or anything, they seem all well and good but I really like Daniel Radcliffe. Whenever I see him in an interview or something he just seems genuinely polite and nice to everyone. I think if you're gonna have that much money and fame, the least you can do is be a good dude and he certainly seems like one.
