High-Intensity Interval Training (HIIT) is a popular exercise approach that involves alternating short periods of intense physical activity with less intense recovery periods. This type of training has been shown to provide numerous benefits, including improved cardiovascular fitness, increased fat burning, and enhanced longevity.

The podcast episodes "#293 - AMA #57: High-intensity interval training: benefits, risks, protocols, and impact on longevity" and "428: Lift Heavy Things, Move, and Get Enough Protein. With Dr. Gabrielle Lyon" discuss the advantages and considerations of incorporating HIIT into a balanced exercise routine. The episodes explore the differences between HIIT and sprint interval training (SIT), the impact of HIIT on VO2 max and longevity, and the importance of a varied exercise regimen and adequate protein intake for overall health and disease prevention.
