How To Improve Your Stretch Reflex

February 23, 2026·25 min·2 clips
Ben explains that heavy eccentrics force 'maximal brain activation' to compensate for lost reflexive support, causing the intense brain fog they feel.
Host John is joined by mentees Ben Moxness and Isaiah Rivera to explore the physiological adaptations and performance benefits of overloaded eccentric training. They break down how super-heavy eccentric loads inhibit reflexive support, increase supraspinal neural drive, desensitize inhibitory mechanisms like the Golgi tendon organ, and ultimately enhance force production for jumping higher.

As heard by us

A dense, practical look at how heavy eccentrics connect physiology to jump training.

Ben Moxness and Isaiah Rivera use overloaded, or accentuated, eccentrics to ask what changes in the body before a jump improves. The discussion stays grounded in stretch reflexes, neural drive, the Golgi tendon organ, and Renshaw cells, while keeping vertical-jump training and…
