The gym is a pretty hellish place to find yourself - usually filled with large men grunting their way through a two-hour workout, lifting weights you couldn't even imagine attempting.
And that's just when it's packed with the regulars - what if you found yourself stood beside an actual superhero? What about Wolverine himself, Hugh Jackman? That'd be enough to bring about a whole new level of insecurity.
Well, after a video was shared on Twitter by the Hollywood star, showing him back to the grind and lifting some seriously heavy weights, fans have been speculating whether this could mean he's planning to make a shock return to the role of Wolverine.
One fan wrote: "Bloggers will say that he's preparing for the cameo in Avengers."
A second follower said: "Why are you training so hard like this? wolverine will return."
A third person replied: "Yes, The Wolverine part of you is saying, you can do it Hugh!"

The hulking Aussie is known for being ripped AF, regularly posting pictures and videos of himself pumping iron, usually trying to get in shape to play his most famous role again.
In recent months there have been rumours that Wolverine could come back with a cameo role in the Marvel Cinematic Universe's upcoming sequel, Avengers: Endgame, set to be released in April this year.
And this isn't beyond the bounds of possibility - now that Disney (which owns the MCU, incorporating all the characters from the Avengers and Guardians of the Galaxy movies) has completed its takeover of Fox (responsible for the X-Men and Deadpool movies), it seems Marvel president Kevin Fiege is keen for the characters to cross over into each other's movies.
Two years ago - *SPOILER ALERT* - he donned the white vest and claws for what appears to have been the final time, in the 2016 blockbuster Logan, which saw Jackman play an ageing version of the popular hero as he ultimately meets a tragic end.
Many haven't quite been able to move past it - Wolverine had been part of the Marvel world for almost two decades, but now he's gone. Some have speculated he could appear in the upcoming X-Men sequel, Dark Phoenix, however.
"Are they going to find a way to get Wolvie in #DarkPhoenix? That'd make a lot more sense than Avengers", one fan wrote.
Others were just impressed with the actor for pushing his body to the limit despite celebrating his 50th birthday, last year.
One fan commended him, saying: "Good job Hugh, you're the best, keep up!!!what a strong and powerful man, you're such an inspiration!!!"
But if another action hero has his way, Jackman might not get the chance to revisit the role. Last year Keanu Reeves revealed that he would like to play the muscle-bound hero in the future.

In an interview with Screen Geek, Reeves was asked about his desire to take over from Jackman as well as whether he would like to be the next Batman.
The 54-year-old said: "Of the two, I'd love to play Wolverine."
The action star added it was not true that he was not available when the roles of Wolverine and Batman came up - rather, he simply wasn't chosen for them.
The Matrix and John Wick star said: "It wasn't that I couldn't take it, it was cast."
