From Phil Heath himself (from Ron Harris's interview)
“I am thankful to finally announce that I am not competing at this year’s 2019 Mr. Olympia contest. As many people have known me throughout my career to compete at the sports biggest event, I will be sitting this one out. as I continue to work on other projects, inside and outside of bodybuilding. I haven’t stopped training, as bodybuilding is something I extremely enjoy doing, but at this point in time, I have chosen to bypass this year’s event.”
