Casey Means on Resistance and HIIT Training: recommends

Dr. Casey Means emphasizes resistance training, high-intensity interval training (HIIT), and endurance work as pivotal for mitochondrial health and healthy aging. Means made the case in the “Beyond Ozempic” episode of the Liz Moody podcast.

Means’s stated reasoning is that exercise is about mitochondrial health, not just calories: muscle work trains the mitochondria that power cellular energy production, and resistance training in particular builds the muscle mass that supports metabolic flexibility. In her framework, movement is a biological necessity — she warns separately that sedentary life “starves mitochondria of movement.”
