HIIT

Meaning

HIIT, or High-Intensity Interval Training, is a structured exercise regimen characterized by alternating short, maximal bursts of near-maximal effort with periods of low-intensity active or passive recovery. This training modality is highly efficient for rapidly improving cardiorespiratory fitness, enhancing endothelial function, and promoting favorable changes in metabolic health. Clinically, HIIT protocols are utilized to promote beneficial body composition changes and significantly improve peripheral tissue insulin sensitivity.
