GET BACK
TO YOUR KOR
Co-founded by a U.S. Marine and former minor league baseball player, Ross and Charles have always prioritized physical fitness without compromise. Just like many of our athletes, we prefer to get away from our phones, get outside, and workout any place and anytime.
STOIK Innovations, centered around its flagship product, KORBOARD, invents fitness and wellness products and services that meet the vision of Simple, Technical, Opulent, Intelligent, and Keen.
Despite the trend in innovative gym equipment, many options require lengthy setup, are too heavy to carry anywhere, and require multiple facets, modifications, and add-ons to complete a full-body workout.
KORBOARD multi-function and full-body exercises center around natural form motions and intensity demanded by athletes.
Both portable and no setup needed, KORBOARD's patented design provides unique anchor-points for rigorous body-weight and resistance workouts at a fraction of the cost.
STOIK Innovations will continue to develop a product roadmap that brings innovations to the wellness and fitness space.

WHAT WE
STAND FOR
Engineer For Longevity
Baltic birch, aircraft aluminum, stainless hardware. Built by hand in a North Carolina woodshop. Sized to outlive the next fitness trend.
Train Anywhere
A rack, a bench, and a cable stack — replaced by a single board. Garage, hotel room, backyard. No excuses, no commute.
Patent-Protected System
The anchor geometry is patented. It is the reason the KORSQUAT, Nordic curl, and dragon flag work on a board this size.
A NOTE
ON THE WORK
We spent two years prototyping this thing before we shipped a single unit. Forty-seven revisions. A lot of shattered birch. The board you order today is the version we finally could not break.
We are a small team. Every board is inspected before it leaves the workshop. Every email is read. If you own a KORBOARD, you are part of how this company runs.
ONE BOARD.
SIX HANDS.
We source FSC-certified bamboo and hard maple from mills within a day's drive. Every panel is CNC-milled, hand-finished, and stamped with a serial number.
Anchors and hardware are machined to 6061-T6 aluminum tolerances. QC tests every unit to 300 lbs of pull before it ships.
No factories overseas. No white-label. Our name is on the back because our team put it there.
JOIN THE
STOIK FAMILY
Any time. Any place. No excuses. This is what we stand for — and what you get when you order.
