Overtraining typically occurs when someone exercises too intensely, too frequently, or without adequate recovery. Among the options provided, the situation most closely associated with overtraining is:
- exercising at a high intensity
While high-intensity workouts can be beneficial, doing them too often without proper rest can lead to overtraining. The other options, such as exercising using the same repetitive motions or exercising more often, can also contribute to overuse injuries or burnout but are not as directly tied to the concept of overtraining as high-intensity exercise. Exercising within your comfort level is generally recommended to avoid overtraining.
