ADVICE

Progress Training Without Always Lifting Max

Train with progressive stimulus within a sustainable framework to avoid tendon injuries in midlife.
Lyon warns muscle outpaces tendons and recommends stimulus progression rather than simply lifting very heavy to prevent cascades after injury.

INSIGHT

Move The Body To Move The Mind

Using the body (cold plunge, sprint, strength) can interrupt repetitive negative thoughts and reset the mind.
Lyon argues maximal physical effort forces focus away from unhelpful narratives and improves mental control.
