Training in hot temps (like Hot Worx) or cold temps: Which burns more calories?

I don’t know about training but standing still you would burn more in the cold.

Burning calories has 0 to do with the temperature. It’s about moving mass (weight) through a displacement. Your goal is not to lose water weight. People are trying to burn fat.


You could argue different temperatures affect different people in different ways while they are working out. Mostly on how they “feel.” If you feel better you might go longer and/or harder and thus burn more calories.

Let someone break down basic life science for you….Jesus, I can’t believe I’m actually taking the time to write this.

Your body uses calories to live. Remeber that BMR business? Yeah, we have to eat to stay alive. Even if we do ZERO activity. Like just staying in bed.

Part of that is maintaining our magic body temperature of 98.7 degrees.

So yes, if it is cold outside and you are in the said outdoors- and not in some mega insulated suit that retains all heat (energy)- your body will have to burn more calories to maintain the temp it needs to live.

I’ve understood you burn more in the cold, because your body has to work harder to stay warm, but that’s just what I heard. I can’t really back that up.

There's some study showing people do more reps if they cool their hands between sets or some such. So I guess based off that you can loosely say that cold temperatures burn more calories.

I reckon you burn what you burn, regardless of outside temperature. I can sit in the sun and sweat, but I'm not burning a bunch of calories more just because my body is trying to cool itself. The only thing I'd suggest is you might burn more calories in the cold simply by virtue of the cold cools your body heat, making you more comfortable. In the heat, you'll give out more quickly.
