I watched this documentary of him this morning.
I'd argue for EIE. I never knew he was so competitive, driven, but not in the way doms are, he seems to have planned out his whole journey which indicates strong , at least stronger than suggestive. It seems he is extroverted and has beta values. I could see an argument for LIE, but since he was always part of a team in bodybuilding (I remember once he was quoted with saying they would motivate each other at the gym as a group), I can't see him as lone 'lone wolf' enough to be LIE.
Another reason for EIE is he has a strong sense of public image, he's always worked hard in that area.
Competitive, driven, team player/motivator, good public speaker, keen on his image, I'd say EIE.
