why do humans sweat? funny how 99.9% of people have no clue why
we sweat cause we evolved to cool ourselves down with sweat glands. dogs for example cannot sweat, so they must cool down by panting or hydrating as much as possible
if you aren't sweating it simply means you aren't getting hot enough. i always laugh at how weight trainers think getting a sweat means they got a great workout.. means nothing. weight training isn't that hardcore where you should finish your workout drenched in sweat and limping out of the gym. if that is how you are training then you are doing it WRONG, or you are one of those social media full of shit guys makes weight training some sort of warrior bs
when i do bikram yoga i sweat out 6-8 pounds easy because we are in a heated room for 90 minutes doing 26 poses and it is brutal. 99% of gym meatheads would not survive 30 minutes of that class
