Overtraining or over-exercising may produce several negative effects on the body that include:

To prevent overtraining, schedule sufficient rest days after long or strenuous workouts. Resting between workouts and decreasing the intensity and frequency of exercises reduce muscular tension and help you feel active while resting after a tough exercise. Simultaneously, do not let too much time pass between training sessions.

Consult your doctor if you have any injuries that worsened over time or did not heal, are experiencing muscular soreness that lasts more than 24 hours, or feeling joint and ligament discomfort regularly. Discuss any concerns with your doctor and coach to ensure appropriate treatment.
