From Pain to Power: A Strength Training Transformation Story with Mac & Gil

In this inspiring strength training transformation story, Niki Sims and Andrew Jackson sit down with Coach Mac McGregor and his longtime client, Gillespie Ferguson, to explore one of the most powerful journeys ever shared on Beast Over Burden. Once a self-described "unathletic" late starter plagued by chronic pain, self-doubt, and years of setbacks, Gillespie rebuilt not just his lifts but his entire understanding of what he was capable of. Through patient coaching, persistent work, and a deep friendship formed through the process, he transformed from a hesitant beginner into a confident, physically capable Coast Guard volunteer on the Isle of Skye.

In this candid conversation, Mac and Gillespie walk through the early struggles of pain and insecurity, the slow technical rebuild of every lift, the psychological work of staying committed through setbacks, and the surprising breakthrough that came years into training. They also share the dramatic impact of Lyme disease, the process of starting over from scratch, and why knowing how to train is the ultimate form of resilience. This episode is a reminder that strength is not reserved for the gifted—it's for anyone willing to start, struggle, and keep showing up.

Whether you're a beginner, someone returning from pain, a coach working with complex clients, or simply someone who needs to hear that transformation is possible at any age, this is an episode you don't want to miss.
