You’ve crossed the finish line — now what? Before you jump into the next training block, let’s talk physiology. In this episode, I’m breaking down exactly what happens inside your muscles, hormones, and metabolism when you don’t take time off (hint: it’s not pretty). We’ll cover how strategic downtime helps restore glycogen, rebalance stress hormones, rebuild muscle, and reignite motivation so you can actually get faster next cycle — not just more tired.

Whether you struggle to sit still or fear losing fitness, you’ll walk away with science-backed permission to rest and a framework for how to use your off-season to come back stronger.
