Signs of burnout in fitness routines include a decrease in motivation, persistent fatigue, and a lack of enjoyment in workouts. Individuals may also experience physical symptoms such as elevated heart rate, prolonged soreness, or increased injuries. When workouts become a chore rather than a source of joy, it indicates potential burnout. Other signs include feelings of irritability or frustration related to performance. To combat burnout, individuals should consider adjusting their routines and incorporating variety to rekindle their passion for fitness while also allowing for adequate rest and recovery.
