As the lab bods know, staying on top of your sweat rate will increase stamina to help you go harder, safely. Here’s how
Don’t overdo it in your quest to replace lost fluids: water overload can lead to dangerous low salt levels. Lay off the caffeine until you’ve cooled off, too, as stimulants up sweat rate.
Sweat rate is not related to calorie burn. Sweating more generally just means your cooling system is efficient, making you well suited to distance runs or other endurance exercise.
If a hard lifting session has your tank top drenched, don’t worry about it. Testosterone is linked to sweat rate, so the more muscle you have, the bigger the puddle on the bench.
The dry run
Don’t sweat it if you don’t perspire much, either. The number of sweat glands varies by individual, as does resting body temperature. As long as you’re working hard, you’re in the clear.
