Came from nowhere.
Now jumping 52.5 inches.
Three years ago Ethan Pimstone couldn’t touch rim — a 5'4" freshman and a 10-hours-a-day gamer. Today he owns one of the highest verticals ever recorded, and he’s documenting the entire come-up in public so you can build yours too.

52.5 inches. On camera. In front of the dunk world.
The jump that broke the internet this week — plus the brothers behind it and the full origin story of how a late bloomer built one of the highest verticals alive.
The most out-of-nowhere arrival the dunk world has seen in years.
This isn’t a genetic-freak story you can’t relate to. It’s the opposite — and that’s exactly why it matters.
5'4" and picked last
Ethan walked into high school at 5-foot-4. Pre-puberty, weak, a corner-three-only player whose freshman-year goal was just to touch the bottom of the backboard. That was his last season of organized ball.
The Fortnite era
What came next was ten hours a day on the controller — the fluffiest, least-active stretch of his life. The jumping gene was there in the background. He just never thought dunking was possible enough to dream about it.
From “LA Fitness Zion” to a real vertical
A late growth spurt, four years in the weight room, and a brother who begged him to train for two straight years. In 2023 he tested 44.5" off zero jump training. Then he finally locked in.
Nobody knew his name — until they did
He showed up to Dunk Camp 2025 knowing no one, expecting a 45. He tested 47.5" and threw his first Eastbay ever the same day, touching over 12 feet. The whole gym asked the same question: who is this guy?
To give every late bloomer the roadmap nobody gave him.
Ethan built world-class bounce with no shortcuts, no early genetics, and no map — just a brother who happened to be a great coach and a willingness to do the boring work right. The mission of this community is simple: prove that explosive athleticism can be built from nothing, at any age, by anyone — and document the whole thing in public so the next kid who got picked last has a place to start.
“I don’t want anyone else to waste three years thinking it’s impossible. The come-up is happening in public now — come build yours with us.”

Jordan Pimstone
Ethan’s older brother Jordan isn’t just family — he’s the architect. A 45-inch tester himself, Jordan has logged every single workout since 2017, engineered his own vertical from 38" to 45", and built the training system the brothers run today.
He coaches athletes full-time on Jump Backs, his self-built program. When you go all-in, this is the brain you’re tapping into — the same one that took a gamer with destroyed knees to one of the highest verticals alive.
Together they’re billed as the highest-jumping brothers in the world — and now they’re coaching the come-up in public.
Questions, answered.
Do I need to be able to dunk already? +
No. The free tier is built for the person chasing their first inch or their first dunk. Ethan literally started as a kid who couldn’t touch rim. You start exactly where you are.
Am I too old / too short / too late? +
The entire premise is that explosive athleticism can be built late. Ethan was a 5'4" freshman who didn’t train for years. The roadmap is the point.
What’s the difference between free and paid? +
Free gets you the community, Ethan’s documented journey, and a starter program. Paid (“Inside the Jump”) gets you the actual Jump Backs programming, jump-video form checks, and live Q&As with Ethan and Coach Jordan.
Can I cancel anytime? +
Yes — month to month, cancel whenever. Founding members keep their locked price if they stay.
