Rob DeCillis got his start in the strength and conditioning world in 2006, when he had the opportunity to train an IFL heavyweight fighter. After a stint with Velocity Sports Performance, he now co-owns Training for Warriors Long Island (Bellmore, N.Y.), where he works with all types of athletes, employing many of the same methods he uses with fighters. In 2011, DeCillis started competing in obstacle course races, and this led him not only to take his training to the next level, but also to coach other obstacle course race athletes.
