Q

What is the main benefit of high-intensity interval training (HIIT) compared to steady-state cardio?

A

HIIT works through unique physiological mechanisms that steady-state cardio does not activate. It promotes a catecholamine surge that mobilizes fatty acids, creates excess post-exercise oxygen consumption (EPOC) for extended caloric burn, and stimulates mitochondrial density adaptation, enhancing fat oxidation capacity.

This is one answer. The complete system — the psychology, the biology, and the method — is in the book.
