The higher your training stress tolerance, the more you’ll get out of the time you put into your workouts. But it’s not the training that makes you fitter and stronger. It’s how your body responds to the training.

You want the stress from training to be high, but within the limits of what the body can handle.

Two great ways to increase your training stress tolerance: improve your work capacity (or in less dickish terms, improve your aerobic conditioning), prioritise sleep, eat real food, and stay cool. As in, find ways to manage your life stress.

Your overall health mirrors the progress you’ll see.
