Exercise

Exercise evidence covers how different training approaches, intensities, and volumes affect cardiovascular health, metabolic markers, and longevity. This hub links to evidence records that compare study designs directly rather than repeating fitness-industry claims.

Moderate Evidence

Is high-intensity interval training (HIIT) better than moderate-intensity continuous training for cardiovascular health?

British Journal of Sports Medicine · 2014

In people with existing cardiometabolic disease, HIIT produces a larger improvement in cardiorespiratory fitness (VO2peak) than moderate-intensity continuous training (MICT) of similar time commitment, with a comparable safety profile in supervised settings. For the general population without existing disease, evidence suggests both approaches meaningfully improve cardiovascular health, and consistency matters more than which one is chosen.
