no because he is not unbbelievably large or unrealistically large after 15 years training say.
dickhead...
What makes you think that one could get this physique after 15 years of natural training ?
I honestly don't think that you've been training that long or are anywhere near that body.
There is something called a natural limit and Markus Rheinhardt is far beyond this.
After some years of training you simply don't get any bigger.
There's no big change if you look at a natural bodybuilder after 10 years or 15 years for example.
