PowerBlock was founded in 1991 by specialty fitness equipment designers Greg Olson and Carl Towley. While searching fro specific needs in the fitness industry, they were drawn to the impractically large amounts of dumbbells they would encounter in every speciality store they visited. It was here that the idea for PowerBlock was born. PowerBlock then created a newly coined “selectorized dumbbell”. Since then, PowerBlock has continued to be a leader in the fitness industry providing a range of adjustable dumbbells, kettlebells and racking systems.
