Most people assume their first attempt will be close to perfect—whether it's a workout plan, a diet, or even a website layout. The truth? You're almost certainly wrong. Brad Barrett learned this the hard way in online marketing: tiny tweaks to wording or design could double conversion rates overnight. Now he and Jonathan Mendonsa are applying that same split testing mindset to something far more personal—your health, fitness, and nutrition habits. In this episode, Jonathan, Brad, and guest MK explore how making one small change at a time and measuring the results can transform your approach to wellness. They discuss the critical role of sleep quality, the pitfalls of deprivation-based diets, and why "never take two days off" might be the simplest fitness rule that actually works. The conversation challenges the all-or-nothing mentality many people bring to health goals, advocating instead for incremental experimentation that reveals what truly works for your body.
