I made a thread a while ago about the 7ft (214cm) Mark "Conan" Stevens, but the thread is ancient now, and he has improved a whole lot since then.
This is his site here:
http://www.conanstevens.comHe has quite a bit of info there.
After a 6 year off setback in the gym he finally started training again only 1-1/2 years ago.
Nerve damage ate the nerves in his right arm and upper right side of his body. His body regenerated the nerves at only 1mm a day, so it took him 6 full years off before he could start training again.
Primarily he is an Actor; bodybuilding is just a successful hobby of his. His primary focus is on acting, and bodybuilding is the secondary agenda on his list. As such he prefers to be compared only to other full time actors physique wise.
Keep in mind that only 2 years ago the entire right upper half of his body looked Emaciated, he really has made a hell of a comeback. He said he still plans on doing a lot more work improving his physique, but he has made a long way for a recovery in only two years.
Here is what he looked like only about 18 months ago:
