I used to feel proud about being drenched in sweat by the end of a workout. I held a common, but mistaken, belief that sweating buckets was helpful in losing fat and getting healthy.

The reality is that one can improve workout performance and results by cooling sufficiently to prevent sweating.

SWEATING IS UNHELPFUL

People often ask: “Should I do lots of reps with light weights, or few reps and heavy weights?”

The answer: neither, actually. There is a more precise measure of exercise performance, and it means you can stop counting reps.
