How does a small-town boy from Mid Wales become the next NSCA President? Follow Ian Jeffreys’ inspiring journey, beginning with his introduction to the NSCA in 1989 as a professional rugby player hungry for knowledge to perform better. Listen as he recounts the thrill of his first conference and why NSCA events are so much more valuable than just what is presented on the main stage. Then, dive into Ian’s career-defining contributions to speed and agility, sparked by his reverse-engineering approach that leverages movement patterns and strong positioning to elevate game speed. Reflect on decades of evolution in our profession, including increased career paths plus the rise of technology and AI — and why they can never replace the true human heart of coaching.
