Which of the following would best describe overtraining?

Overtraining is best described as exercising too frequently without allowing adequate recovery time for the body. Engaging in high volumes of training without sufficient rest can lead to various negative effects, such as fatigue, decreased performance, increased risk of injuries, and psychological symptoms like increased anxiety or irritability. The body needs recovery to repair muscles, restore energy, and prevent the depletion of essential nutrients.

The other options illustrate different aspects of fitness and training practices that do not imply the risk of overtraining. Exercising at a moderate intensity regularly promotes a balanced approach to fitness, while alternating between rest and workout days helps to enhance performance and reduce the chance of overtraining by incorporating necessary recovery. Participating in seasonal sports provides structured breaks between training phases, which also aids in preventing overtraining. In contrast, exercising too frequently without recovery undermines these beneficial practices, ultimately pushing the body beyond its capacity to recover.
