7. Persistent injuries or muscle pain
Extended muscle soreness and injuries that don’t heal are also signs of overtraining. You may have chronic injuries or nagging injuries that linger for a long time.
Rest between workouts is vital to recovery. It’s harder for your body to heal when too much stress is placed on it.
8. Decline in performance
Overtraining can cause your performance to plateau or decrease rather than improve. You may find you have less strength, agility, and endurance, which makes it more difficult to reach your training goals. Overtraining can also slow your reaction time and running speed.
