Buckle

Prepare (to make ready in a general, calm, and planned way) contrasts with buckle, which means to get ready with urgent, intense effort, often under time pressure or in a crisis. Buckle implies stress, immediate action, and a sense of “now or never,” while prepare suggests a broader, less frantic timeframe.

A young athlete has been training for months, but the night before the championship, he panics. Instead of sleeping, he stays up all night reviewing techniques, tightening his shoes, and visualizing every move. He is not calmly preparing; he is under extreme pressure, forcing himself to focus because there is no time left. What is the athlete doing? He is buckling down for the final race.
