Synopsis

There are over 600 individual muscles in the human body. Who has time to train all of them when the world's ending?
In the world of professional arm wrestling, there's only one part that matters: the arm. At least, that's how Chadwick sees it. His commitment to that idea has made him a freak of nature, one whose right arm is large and muscular enough to make weightlifters and strongmen do a double-take. Just how he likes it.
His dedication is rewarded when, just as the world goes to hell, he is granted the ability to exclusively strengthen specific parts of his body. What follows is gains. Lots and lots of gains. And with an ominous portal spewing monsters into his reality, it's not a moment too soon.
What to expect:
- System Apocalypse
- Strong to stronger MC
- Kinda dumb main character with smart sidekicks
- One particular number going BRRRR
- No harem
- A completely reasonable amount of puns and shenanigans
