The Kid Who Did Not Grow

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 Lost Years

What came next was the Fortnite era: 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.

The Switch

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 and went from “LA Fitness Zion” to a real vertical.

The Arrival

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?

The Numbers Today

Today Ethan owns one of the highest verticals ever recorded, with the 52.5 inch record jump captured on camera by Dunkademics. The dunk package keeps growing: clean windmills, Eastbays, and 360 variations, all built from the ground up.

Coached by His Brother

Ethan’s older brother Jordan Pimstone is not just family, he is the architect. A 45-inch tester and full-time jump coach, Jordan has logged every single workout since 2017, engineered his own vertical from 38″ to 45″, and built Jump Backs, the training system the brothers run today. Together they are billed as the highest-jumping brothers in the world.
