Myelin

Definition

The fatty sheath insulating nerve fibers, increasing signal speed. More myelin = faster neural communication = better strength and power output. It's why practice makes perfect.

Example Usage

Consistent strength training builds myelin around motor nerves, explaining rapid early strength gains even without muscle growth.

Origin

Neuroscience term; applied to exercise science and athletic training.

Fun Fact

The majority of strength gains in the first 2-4 weeks of training are neural (myelin + motor unit recruitment), not muscular.

kata

A choreographed sequence of movements practiced in martial arts that looks like fighting an invisible opponent who's really bad at dodging. These pre-arranged forms teach technique, balance, and muscle memory while making practitioners feel like they're in a kung fu movie. Performing kata at tournaments involves being judged on precision and power, which is martial arts' way of combining dance recital anxiety with actual combat training.

press

In fitness contexts, any exercise where you push weight away from your body, because apparently "push" wasn't fancy enough. The bench press, shoulder press, and leg press are all variations of this movement pattern that gym bros use to measure their self-worth. Not to be confused with the media press, though both can make you feel equally crushed.
