Exercise is crucial for health, but overdoing it can lead to overtraining and harm your body. When workouts exceed your recovery capacity, signs like persistent fatigue, muscle soreness, insomnia, mood swings, and decreased performance may appear. Training for more than 1.5 to 2 hours daily without sufficient rest can weaken the immune system and increase the risk of injuries. Instead of pushing too hard, focus on a balanced routine with adequate rest days, proper nutrition, and hydration. Listening to your body and allowing time for recovery ensures sustainable fitness progress without burnout or long-term health issues.
