Visceral Fat Science
→Fat-burn zone 106–124 bpm is where fat oxidation peaks for your age
→HIIT (Day B) creates 24–48hr afterburn that preferentially targets visceral fat
→Leg day (Day C) burns the most calories — largest muscle groups in the body
→Visceral fat responds faster to exercise than subcutaneous fat
→Sleep 7–9 hrs — cortisol from poor sleep directly increases visceral fat storage
