What if the key to peak performance and longevity isn't just in your workouts, diet, or sleep, but in how well your body handles stress? Optimizing your health isn't just about the latest supplements or fitness trends, it's about understanding your nervous system, heart rate variability (HRV), and how small daily habits shape your resilience over time. Most people try to eliminate stress, but the real goal is building the ability to recover faster and adapt better.

In this episode, I sit down with Salim Najjar, an HRV expert and biohacker who took his health to the next level by learning how to regulate his nervous system. We break down why stress is a signal, not a problem, how HRV can predict when your body needs rest before you even feel it, and the most effective ways to improve recovery, sleep, and overall well-being.

Salim is a biohacker, entrepreneur, and founder of Sound Beverages, a company focused on functional health drinks. After years of pushing his body with extreme training and biohacking, he discovered the missing piece: HRV as a measure of how well the body adapts to stress. Now, he teaches others how to improve their HRV, manage stress more effectively, and use data to optimize performance and longevity.

If you're looking for real, actionable strategies to train your nervous system, boost recovery, and perform at your best, this episode is for you!

Let's dive in.
