The phrase "run out of steam" is an idiomatic expression that refers to the state where one's physical or mental energy, motivation, or enthusiasm starts to wane or diminish, usually after an intense or prolonged effort. It is commonly used to describe a situation in which a person or a group loses the ability to maintain the same level of activity, productivity, or intensity they had initially displayed.
Metaphorically, the term derives from the image of a steam engine running out of its power source or fuel, causing it to gradually slow down and eventually come to a halt. When someone "runs out of steam," it implies that they have reached their limits, exhausted their resources, or depleted their reserves, leaving them incapable of continuing their current pace or effort.
This expression is frequently used in various contexts, such as work or educational environments, sports, or personal endeavors, to depict a temporary or permanent decline in performance, focus, or motivation. For instance, an individual who has been tirelessly studying for an exam may "run out of steam" when they start experiencing mental fatigue or a lack of concentration. Similarly, an athlete who has pushed themselves to their physical limits during a race might "run out of steam" as their endurance diminishes, causing them to slow down or become unable to continue altogether.
Overall, "running out of steam" implies the natural human capacity for energy to dwindle, highlighting the need for rest, rejuvenation, or motivation in order to regain one's strength and resume a previous level of performance.
