REHIT – Reduced Exertion High-Intensity Training

Imagine you're a hunter in the wild, chasing down prey for survival. You sprint at full speed, pushing your body to the limit. But within seconds, your glycogen stores are depleted—your body now faces a choice: shut down or adapt. At this moment, AMPK (your internal energy sensor) pathway starts to kicks in, detecting the energy crisis. Your probably thinking, what the hell is AMPK? Well, it's something that'll keep you brimming with energy, it'll boost your immune system, it'll help you lose weight by burning fat, but most importantly, it'll keep you young by cranking up your mitochondria, supporting autophagy, and putting chronic inflammation on the back burner, if you activate it. And in this video, I'll show you how to do just that. Exerting yourself to tolerable levels, sends a signal to your cells: “We need more energy NOW.” is so, so important for your metabolic health, but also a key to longevity. Your body responds by unlocking stored fat, increasing glucose uptake, and activating fat-burning pathways to keep you moving【1】. But survival isn't just about burning fuel—it’s about lasting longer, running faster, and recovering better. In the case of a hunter, it’s pulling on his resources to catch his prey and live to fight another day. This is also where PGC-1α steps in, triggering the creation of new mitochondria—your body’s power plants【2】. More mitochondria mean greater endurance, better energy efficiency, and faster fat oxidation the next time you sprint. This biological hack is exactly what happens in REHIT 📌 How to Perform REHIT 🔹 Step 1: Warm up to prevent injury. 🔹 Step 2: Follow this protocol for 7 minutes: 1️⃣ 20 sec FAST (all-out sprint) 2️⃣ 3 min SLOW (very low-intensity recovery) 🔄 Repeat twice, followed by a 3-minute cooldown. ✔ REHIT Maximises fat loss, endurance, and metabolic adaptation with minimal time commitment【3】.
