Why HIIT Works
HIIT improves:
✔ VO2 max
✔ Insulin sensitivity
✔ Fat oxidation
✔ Cardiovascular health
✔ Time efficiency
It creates an “afterburn effect” — your metabolism remains elevated post-workout.
But remember:
HIIT is powerful.
Overdoing it is not.
Balance intensity with recovery.
Fueling HIIT Properly
High-intensity training requires:
• Adequate protein
• Balanced carbohydrates
• Hydration
• Recovery nutrients
Under-fueling leads to:
Hormonal disruption
Poor recovery
Increased cravings
Plateaued results
That’s why structured nutrition matters.
