## Resource

Are light runs (Zone 2 runs) better than heavier workouts? Sophie goes on a semi-manic tangent in her most enthusiastic episode yet to answer whether less intense exercise might actually help your fitness level, aerobic threshold and mitochondrial efficiency. Also, Chris tells a funny marathon story and a viewer question tries to fact-check to the fact checkers on whether walking and running burn the same amount of energy.
