Episode Details

Everywhere you look, the fitness world is selling extremes — train harder, do more, chase the most intense program on the feed. But for a busy adult trying to stay strong and capable around work and family, that's a recipe for burnout, not results. So what actually works, and lasts? This episode makes the case for functional fitness: training that builds a body that's useful for real life, not just for the mirror.

Jesse sits down with Jon Little, President and COO of REP Fitness, to break down what functional fitness really means, how it's evolved, where it fits among all the options out there, and why the way you train and the way you fuel your body can't be separated. It's a practical, no-hype conversation about building strength you can sustain for life — and the role good nutrition, like the kind Purist is built around, plays in making it possible.

If you've ever felt lost in the noise of programs, classes, and trends, this one gives you a clear, honest framework for choosing how to train.
