Signs of overtraining can include prolonged fatigue, decreased performance, and persistent muscle soreness. Other symptoms are mood swings, irritability, and sleep disturbances, which can all impact overall well-being. Overtraining can disrupt the body's natural recovery processes, leading to injuries and setbacks in fitness goals. If an individual experiences these signs, it’s important to reassess training intensity and volume, allowing for adequate rest and recovery time to restore balance and maintain long-term success in fitness.
