It is interesting that after over 40 years since Arnold Schwarzenegger retired from bodybuilding, nobody has better chest than him. Even till this day, there are some guys who have really good chest for example. Roni Coleman, his chest was humongous but so was everything else, so in comparison to the other body parts, his chest wasn't as dominant. Today we have classic visit mr. Olympia champion Chris Bums that has phenomenal chest but it's not at the level of Arnold Schwarzenegger. Franco Colombo had great upper chest but not overall chest. Feel he'd had crazy looking 3D chest but his clavicles were pretty narrow so he was narrowing the shoulders and you would definitely pay more attention to his arms instead of his chest. There are two guys that compare to Arnold Schwarzenegger and that's Markus Rool and Branch Warren but still if you talk about the best chest of all time, it has to be Arnold Schwarzenegger. Why is this his style of training or his genetics simply whatever you guys think, tell me in the comments section.
