High-Intensity Interval Training (HIIT) for rapid blood sugar drop
Berg opens with HIIT as the first and one of the most effective tools for blood sugar control. He emphasizes that the volume needed is minimal — not a full workout, but merely minutes of effort. The core idea is that forcing rapid muscle contractions acts as a powerful glucose sink, pulling sugar out of the blood almost immediately. This makes HIIT a practical emergency lever for anyone who has just consumed a large carb load and wants to blunt the impending spike. He lists accessible examples to show that specialized equipment is unnecessary.
Skeletal muscle contraction triggers insulin-independent GLUT4 translocation to the cell membrane, allowing glucose entry without requiring insulin. During high-intensity efforts, glycogen stored in muscle is rapidly used, drawing glucose from the blood to replenish it. This dual effect rapidly clears circulating glucose.
Anytime you force your muscles to contract, this type of exercise will deplete any excess sugar you have in your blood very quick.
