Overtraining without adequate recovery can lead to burnout, decreased performance, and increased risk of injuries. Symptoms include persistent fatigue, mood swings, and diminished motivation. When the body does not have time to recover, it can result in physiological stress, which may lead to imbalances in hormones and immune function. Ensuring proper rest, nutrition, and sleep is critical for recovery, helping to maintain physical and mental health, enhancing performance, and preventing long-term damage.
