Christian McCaffrey’s latest workout post took a predictable turn once football fans got their hands on it.
The San Francisco 49ers star shared a training clip that quickly started making the rounds online, with viewers comparing one of his movement drills to a Call of Duty zombie crawl. McCaffrey did not ignore the joke, either. He reposted one of the viral reactions to his Instagram story, turning a hard-core offseason workout into a social media moment.

That is what gives this one some staying power. The clip was already getting attention because the drill looked so unusual. Once McCaffrey showed he had seen the jokes and was willing to laugh at them, the post became more than just another workout video.
McCaffrey leaned into the joke after the clip took off
The video shows McCaffrey moving low to the ground in a controlled crawl, keeping his body almost parallel to the grass while inching forward. It is the kind of movement clip that looks almost unnatural in real time, which helps explain why so many reactions went in the same direction.
One repost that McCaffrey shared compared the drill to keeping “the one zombie” alive until your loot is set up, a clear Call of Duty reference. Another social post joked that McCaffrey looked like he was preparing for a Spider-Man role. Others simply treated the clip like proof that the 49ers running back is operating on a different physical level than most athletes.
CMC is one of the best athletes we’ve ever seen.
Many people don’t realize how hard this is.
🤯🤯🤯
Fans expect elite players to post offseason work. They do not always expect the player to join the punchline when the internet turns the workout into a meme.
Why this workout video caught on so fast
A lot of training clips get praise. Fewer get turned into a joke format that spreads across multiple football accounts.
This one worked because the movement itself is instantly striking. McCaffrey is not just lifting, sprinting or doing a standard ladder drill. He is performing a low, controlled crawl that looks difficult, awkward and weirdly cinematic all at once. Even people who do not know the purpose of the drill can tell it requires unusual strength, balance and body control.
That is why the reactions landed. The Call of Duty comparisons were funny, but they also doubled as a compliment. Nobody was mocking McCaffrey for being out of shape or doing something sloppy. The joke was that he looked like a video game character because the movement seemed almost absurdly hard to replicate.
For a player like McCaffrey, that kind of reaction fits his reputation. He has long been viewed as one of the NFL’s most demanding trainers, and clips like this tend to reinforce that image even when they get packaged as memes.
What 49ers fans will care about most
For 49ers fans, the real takeaway is not the zombie jokes. It is that McCaffrey once again looks fully immersed in his training work, and his latest post gave another glimpse into the kind of movement prep that has helped make him one of the league’s most dynamic offensive weapons.
The internet always flattens these clips into one-liners, and that is part of the fun. But the reason the video blew up in the first place is simple: the drill looked brutally difficult, and McCaffrey made it look fluid enough for fans to start comparing him to a video game animation.
By reposting one of the best reactions himself, McCaffrey helped the moment travel even further. Instead of shutting down the memes, he validated them.
That is usually how a viral sports clip grows legs. First the athlete posts it. Then the football world reacts. Then the athlete reacts to the reaction, and suddenly the story is no longer just about training. It is about personality, timing and the way a star player can turn a grueling offseason drill into a joke everyone wants in on.
For McCaffrey, it was a pretty good reminder of two things at once: he is still one of the NFL’s biggest workout curiosities, and he knows exactly how to play along when the internet notices.
