🚀 Norwy: Torch Fat & Strengthen Your Heart
Unlock the most scientifically effective workout for fat loss and longevity. Norwy simplifies the world-renowned Norwegian 4x4 method, providing customized plans that take you from total beginner to peak performance. No fluff, no ads—just results. 🔥
🏃♀️ What is the Norwegian 4x4 Protocol?
While our app scales the intensity to match your current fitness level, the "Gold Standard" protocol used by elite athletes looks like this:
🕐 5-minute warm-up
🏃♂️ 4 intervals of 4 minutes (at 85–95% max heart rate)
🚶♂️ 3-minute active recovery between intervals
🧘 5-minute cooldown
New to training? Don’t sweat it. Our app includes specialized programs that gradually build your stamina, guiding you step-by-step until you can tackle the full protocol with confidence. 📈
🏃♀️ Why It’s the Ultimate Health Hack?
The 4x4 isn't just a workout; it's a metabolic powerhouse. It is scientifically proven to be the fastest way to increase your VO2 max—the #1 predictor of a long, healthy life. For those focused on weight loss, the high intensity triggers a massive "afterburn effect," keeping your metabolism spiked and burning calories long after you've finished your shower. You’ll feel the difference in your energy and endurance in as little as 4 weeks. 💨❤️
