Brendan Cosso,  a visionary in the fitness industry, renowned for his innovative approach to bodyweight training. As the founder of the World Calisthenics Organization (WCO), Cosso has played a pivotal role in transforming calisthenics from a niche form of exercise into a globally recognized sport. His creation, the CrossCore Rotational Bodyweight Training System, represents a groundbreaking method that leverages bodyweight exercises to enhance strength, flexibility, and overall fitness through unique rotational movements.

The CrossCore® Rotational Bodyweight Training System, developed by Cosso in 1996 and patented in 2012 (US-8152704-B2), introduced a novel training product and philosophy focusing on rotational movements. CrossCore was designed using a pulley system to engage core muscles in ways traditional exercises do not, promising not only physical strength but also functional fitness that improves everyday life activities. His methodologies have been adopted by athletes, fitness enthusiasts, and even integrated into rehabilitation programs for their comprehensive benefits.

After Selling CrossCore® Cosso’s deeper journey into the fitness world was marked by his inception of the WCO, an organization dedicated to promoting calisthenics not just as a physical activity but as a competitive sport. The WCO, under his leadership, has organized events like the Battle of the Bars®, which has become a cornerstone event for calisthenics enthusiasts worldwide, showcasing the sport’s athleticism and artistry.
