My dad, Jim Duffy, a former hockey player, built The COBA Board as a solution-based product to keep training hard and maintain strong legs and glutes as he got older. Determined to maintain strength through his 60s and beyond, he set out to find a smarter way to train while going easier on his knees and joints after years of sports injuries.

As a former fashion editor and entertainment host, I’d seen every wellness trend and tried nearly every workout. Fitness had always been a part of my life, but I still struggled to find something that worked at home. When I saw what he created and started working out on it myself, I knew women would love it — not just for performance, but for sculpting lean, strong legs and glutes safely and effectively. Together we turned his basement prototype into a patented, science-backed innovation designed for real people of every age and fitness level.

We launched on Kickstarter and today we’re still proudly family-owned and operated. What began as a search for smarter, more effective movement has grown into a joint-friendly, science-backed innovation trusted by beginners, professional athletes, physical therapists and wellness enthusiasts worldwide.

From our family to yours, we can’t wait to see you on board!
