Does sweating more during a workout mean you’ve burned more calories or had a hard fat burning workout?
NO! Your body produces sweat when it is trying to cool down its core temperature. The more sweat, the hotter your core temperature, by no means does it gage whether or not you had a decent workout. In fact the more fit you are, the less likely you are to sweat as much. This is because your body has conditioned itself to exercise. Therefore, it takes higher intensity exercises to heat your core temperature to create sweat.
