Phil Heath, Dennis Wolf and Top Contestants Competing at 2015 Mr. Olympia

The end of a journey and the rights to a Sandow trophy begin anew in Las Vegas this weekend as Phil Heath and the best bodybuilders the globe has to offer take the stage at the 2015 Mr. Olympia.

For Heath, it's a chance to win a fifth title in a row and inch closer to eight-time winners Lee Haney and Ronnie Coleman.

For the rest of the competitors, it's a chance to make a serious push at an upset with Kai Greene, Heath's biggest competition and rival, out of the show. Below, let's take a look at Heath and the biggest names to know before things get underway.

Full qualified list and point standings available at Olympia's official website.

Top Contestants

Shawn Rhoden

With Greene out of the picture, the up-and-coming Shawn Rhoden sees his odds increase more than one would have thought possible just a month ago.

Rhoden has been on the rise for a while now, placing fourth at the competition in 2013 and third last year behind Heath and Greene. The Kingston, Jamaica, native might be 40 years old, but it's hard not to notice his continued rise, breaking into what has been a two-man show for quite a while now.

RX Muscle was one of many to offer an opinion on Rhoden's arrival in Las Vegas:

Conditioning has seemed to hold Rhoden back in past years, but he's been on the rise for a reason.

If there's going to be an upset, it figures to come this year before Greene gets back in the fray next year and others begin to emerge. Rhoden has what it takes to dethrone Heath; it's just a matter of executing on stage at this point.

Like Rhoden, Dennis Wolf has come a long way in just a few years.

The owner of third- and fourth-place finishes as of late, Wolf has become a fan favorite and needed to tune up a few things to break into the top two. With Greene gone, he could very well slide into No. 2 or give Heath a run for his money.

For Wolfe, he's not content with how the leaderboard shaped up the past couple of years, per RX Muscle:

It takes near-perfection to take down Heath, especially when a champion gets on a roll and wins a few in a row.

For Wolf, it's beginning to seem like now-or-never territory. He's well known and continues to address the areas that have caused him to come up short in recent years. With the door somewhat open, it will be quite entertaining to see what he does this weekend.

Phil Heath

Believe the hype when it comes to Heath. 

The man's a four-time winner at the age of 35 for a reason. He's on pace to keep his career rolling and match the greats, especially if he can use this year as a way to put some distance between himself and the up-and-comers. That is just what he plans to do, as he told Flex Online:

"

It’s definitely not a two-man show. There are many great athletes out there. It’s my job to knock the up-and-comers down. I have to be ready to do the work, and it’s not easy because they all want to kick my ass out there. In the end, though, it’s not about beating the others. I have to respect myself, and I have to compete against myself. To win, I have to be better than Phil Heath.

"

With his borderline equal out of the picture, Heath stands tall above the rest in pre-judging, with only the above two names coming on close from an observer's standpoint.

Then again, Heath isn't one to count out a serious push from the field, so neither should fans. Win No. 5 seems a sure thing, but for Heath and anyone who has competed here before, there's a big difference between talking about it and going out and doing it.
