2. Sweating more means you got a better workout and/or losing more weight.
The function of sweat is to cool the body down and regulate internal temperature. There are several non-exercise related factors that cause a person to sweat, including, being overweight, outside temperature, and heavy consumption of caffeine and/or alcohol. Any immediate weight loss occurring by sweating is water weight that will promptly be gained back once you rehydrate yourself. While some workouts make you sweat more than others, there are some exercises such as weight training and long distance walking that do not cause a person to sweat as much.
That is not to say that sweating has no benefit beyond cooling. It can temporarily raise metabolism, allow for toxins to be released from the body as well as result in smoother and softer skin with proper cleansing. However, sweat does not directly signify a better workout or result in more weight loss.
