All eyes, though, are going to be on Phil Heath, who is the five-time defending champion dating back to 2011. 

He is just one of five men to ever win the competition five or more times and with a win on Saturday, Heath could tie Dorian Yates for fourth-most Mr. Olympia wins of all time with six. 

Yates, who hailed from Great Britain, won his six titles all in succession from 1992-1997. 

Even with five titles under his belt, Heath has shown no signs of slowing down:

There is also one other former Mr. Olympia who will be in the field in Dexter Jackson, who took the title in 2008. 

His win halted the run of Jay Cutler, who won from 2006 to 2007 and 2009 to 2010:

Jackson also finished in second last year to Heath. 

He will turn 47 years old in November, but Jackson is still putting up wins in 2016, with victories at the New York Pro and Arnold Classic South Africa. Expect for him to be in contention on Saturday as well.
