The history of Diamond Fitness began in 2010, when JK Fitness, a company specialised in sports equipment with twenty years of experience, decided to debut in the professional fitness sector under the banner of a single value: quality. Year after year the ambition of the brand grows and the team that will bring Diamond Fitness to be an excellence in professional fitness equipment takes shape. At the head of the team is the Project Manager Jacopo Castellani, whose many years of experience in the field of athletic preparation and metabolic training is combined with a deep dedication to the gym world.
