1. Short-term over-exercising symptoms
Abnormally fast heartbeat, dehydration, weakness, dizziness, extreme shortness of breath, and disorientation. These symptoms quickly tell you that your workout plan is clearly exaggerated (or at least that your body is not ready yet for such an intense session).
Most people experience one of these symptoms the first time they hit the gym for a cardio workout after months – or even years – without exercising. Take things slowly because your body needs to adapt first.
