It depends on whether you are talking about aerobic training (running, cycling) or anaerobic training (weight lifting, body building) but they do have many symptoms in common:

Athletes may also experience mood changes, such as irritability or anxiety, as well as disrupted sleep patterns. Monitoring these symptoms is crucial for preventing long-term physical and mental health issues.

HR is the single most effective indicator of overtraining. If you perform the same activity as you did a few weeks ago and your HR is significantly higher you are probably overtraining. Also, if you feel weaker and less willing to do your exercises you might be. You really have to be a serious athlete to reach this level however. Its not common.

Overtraining
Overtraining occurs when an individual engages in excessive physical training without adequate rest and recovery, leading to a decline in performance and increased risk of injury. Signs of overtraining include persistent fatigue, decreased motivation, increased irritability, and prolonged muscle soreness. An example of overtraining might be an athlete who trains intensely every day without taking rest days, resulting in burnout and diminished athletic performance. Proper balance between training, recovery, and nutrition is essential to avoid this condition.
