Cheath = Palumboism. Won't recover.
Phil just turned 41 on Friday...I don't think he can do much to improve at this stage in the game, given he has already "maxed out". The most he can do is come as close as possible to maintaining what he has, trying to keep his waist as under control as possible, remain injury-free so he doesn't see an entire side of his body atrophy like we saw with Ronnie in 2006, and to a much greater extent - in 2007, and maintain the highest level of conditioning he can while doing all of that.
In other words, what he did this weekend is most likely the best he can do - literally the best he was able to do, so I can't knock the guy for being lazy, or not putting the time in. It's just that he won't be able to respond at 41 like he did at 31. Ronnie's last Mr. Olympia victory was in 2005, when he was 41.
Although...it's interesting to think that Shawn Rhoden was 43 when he won in 2018.

Rhoden still holds the record for oldest Mr. Olympia, having beaten Chris Dickerson's longstanding record, who was also 43 when he won in 1982, but some months older than Rhoden's 43.
I had Phil in 2nd from the pictures that I saw, but I only looked over about 3-4 shots, lol. I would think anything between 2nd and 4th would have been fair, and if he got 3rd, that sounds about right to me. Good for him...but too bad it's now going to be basically impossible for him to tie Ronnie and Lee for eight Sandow trophies. I'm sure he wanted that, but...looks like he will have to be content tying Arnold's personal record for seven Olympia wins.
