The Threshold Lab
The Threshold Lab is where “aha” moments and insights go to lift weights. Each episode cracks open a fundamental principle from the world of high performance and aims to transform how you think, work, and lead. Think of it like unlocking a door you’ve passed a hundred times, only to find it opens into a whole new way of thinking. If you're into mindset, growth, and the occasional mental mic drop, you're in the right lab.
Zach Brandon is a coach, speaker, and thought leader blending principles from psychology, coaching, and high performance to empower others toward personal and professional excellence.

In this episode, we explore the hidden cost of restlessness.
