What does overtrained mean?
Overtrained means trained excessively, usually beyond the point where further practice improves performance or well-being. The term is especially common in sport, fitness, education, and animal training, where it may describe an athlete, performer, student, horse, or dog subjected to too many demanding sessions. It often carries a mildly critical implication: more coaching or repetition has stopped being useful and may be causing fatigue, loss of motivation, stiffness, or a decline in results. Overtrained can also function as the past tense and past participle of overtrain, as in “the coach overtrained the runner.” The word is concise and forceful because it compresses both excess and its likely consequences into a single adjective. Its related noun, overtraining, is widely used for the condition or process itself, while overtrain names the corresponding verb. In general usage, overtrained should be reserved for cases where training is clearly excessive, since simply intensive but appropriate preparation is better described as hard training or intensive training.
Having been trained excessively, especially to a point where performance, condition, or motivation has deteriorated.
"The overtrained sprinter could not match her earlier pace."
Common in discussions of athletes, performers, students, and animals. It usually suggests that additional training is no longer beneficial.

"The coach overtrained the horse before the important race."
