Dr. Zach Guiser explains that while sprinting is the ultimate tool for speed, peak performance is limited by the "weakest link" among various musculoskeletal and neurological subsystems. He details how sensory inputs from the eyes, inner ear, and joints are processed by the brain to determine how much power the motor cortex is allowed to output. The episode concludes with a nine-point training framework designed to address everything from tendon stiffness to automatic brainstem drive, ensuring athletes remove the internal "governors" that hold back their speed.
