The potential downsides of exercise addiction include increased risk of injury, social isolation, and neglect of personal responsibilities. Individuals may prioritize working out excessively to the detriment of their mental health and relationships. This compulsive behavior can lead to physical burnout, overuse injuries, and a distorted body image. It may also result in anxiety or depression when not exercising. Recognizing these negative patterns is crucial for maintaining a healthy relationship with fitness and ensuring a balanced lifestyle.
