Warning signs: when to stop and see a professional
The app doesn't give medical advice. Some signs mean you must stop training and talk to a doctor.
Stop and seek medical help if you have
Chest pain or tightness, fainting or nearly fainting, unusual palpitations, shortness of breath out of proportion to the effort, or dizziness during or just after exercise. With these symptoms, don't return to training without a medical assessment.
Fever or general symptoms of illness (body aches, feeling unwell): don't train with intensity.
Signs of overtraining or low energy
Fatigue that doesn't go away with rest, performance falling for weeks, disturbed sleep, mood changes, frequent illness. They can point to insufficient recovery or low energy availability (eating less than your training demands), which affects bone, hormonal and immune health.
Talk to your coach to ease the load and to a health professional (doctor, dietitian) to find the cause.
How Zenvit uses this: When your data shows signs of overload, the app warns you, takes you out of the rankings and recommends easing off; it never suggests training more.
