I think the 2019 Olympia is going to be very interesting.
I think that the Sandow will be very slippery for Rhoden, I think he will be a single year winner, he wll be 44-1/2 years of age for Olympia 2019.
Phil Heath will be super motivated and has a good chance of coming back for his 8th non-consecutive Olympia championship, come contest time 2019, he will be 39-3/4 years of age..
If there was ever a time for Kai Greene to comeback, it is RIGHT NOW. IMO it was a mistake for him not to be there this year, he could have won the big show. He still has all of his size, but he is also battling an abdominal distention issue as well. He would be just over 44 years f age come Olympia 2019.
Mamdouh Elssbiay "BIG RAMY" could also be a contender, but he needs to get his conditioning and show prep under control. His 6th placing was a big disappointment. As much as I hate to say it, Big Ramy's language skills are hurting his chances as well. For Olympia 2019, he will have just turned 35 years of age.
Then there is Roelly Winklaar, "The People Champ" of the 2018 Olympia. He is proof that improvements of the abdominal distention are indeed possible. For next years Olympia he will be 42 years of age.
James "Flex" Lewis following his retirement from his 7 year reign of the IFBB "212 lb" class is apparently stepping up to the Open class. Many said that if he competed in the Open class for Olympia 2018 that he would have busted into the top 5, some said top 3, but I don't know about that.
Here's a good video with some greats of the bodybuilding world including: Dave Palumbo, Chris Aceto, Milos Sarcev, Aaron Singerman, , Chris Cormier, Tom Platz and 1983 Mr. Olympia Samir Bannout.
