I created the COBA Board after a sports injury had me searching for a safe way to strength train my legs without straining my knees,” said Jim Duffy, CEO of Pure Glutes. “After creating the COBA Board Glute Trainer, we had it tested to ensure it was not only safe, but effective at targeting the hard-to-build glutes and hamstrings. We were proven right.

Jim Duffy: From Concept to Creation

Founded by Jim Duffy, former Division I hockey player, along with his daughter Jordan, a lifestyle editor and fitness buff, Pure Glutes LLC developed, tested and patented a more effective way to build a better butt with the revolutionary COBA Board Glute Trainer.

The COBA Board's patented counterbalance and functional resistance help to shape, tone, and build difficult to activate glute muscles faster, safer and more effectively than traditional methods.
