1128 gymnázō (from 1131 /gymnós, "to train, naked or wearing a loin cloth") – properly, naked or lightly clad, as with an ancient Greek athlete in a sporting event; (figuratively) to train with one's full effort, i.e. with complete physical, emotional force like when working out intensely in a gymnasium.

["Gym" and "gymnasium" come from this same root.]

1128 /gymnázō ("exert intensely, like a pro-athlete") presumes full discipline, necessary to be in "top working condition" (full agility, skill, endurance). This is gained only from constant, rigorous training (exercise). 1128 (gymnázō) conveys acquiring proficiency through practice – regular exercise with graduated resistance (the physical element is also included with the spiritual of being in "God's gymnasium").
