It’s the age old question, but one we’re still confused about.

A lot of people equate sweat to how hard they’re working. However it’s not an accurate representation of the effort you’re putting into an exercise session.

Sweat is the body’s super-effective cooling system, and we naturally perspire a litre of water on a rest day. And, besides, some people’s genetics mean they sweat more easily than others.

It just means how hot your body is. So if you’re jumping on the spot in a hot room, you’re going to start sweating. If you’re working harder in a cold room, you might not sweat but you’ve still put in more effort.
