Like working out in a room that's like unreasonably hot would be less advantageous from a performance standpoint.

And there are nuances like if you're, I don't know, acclimatizing to go do some kind of like a race or something in a hot area.

Like I used to ride my bike in a really hot room when I was getting ready for Ironman Hawaii.

Right.

Or if your number one goal is like sweating, heat shock proteins, cardiovascular stimulus.

But I would argue that like if you're in the gym gym, you should be in the gym to build strength and power.

And if you want to like get really good cardio fitness, yeah, go ride your bike in a hot room or hit the sauna.

It's better for you different.

Yeah.

Like, it's better for you cardiovascularly.

And, like...

Everybody thinks about the gym a little bit differently, but I primarily think about the gym as a place to build muscle and get strong and develop power and separate the cardiovascular component from that.

Like if I wanted the best of both worlds, I would go to a gym where it was like 65 to 70 degrees in the weight training area and then eat the most out of my cardio training.

There's another room that's like kind of hot that you could go to your cardio in.

So you know what I'm saying?

It kind of depends on what your goals are.

That's a great word.

You're right.

That heat would allow you to do that, but—

You can pretty quickly cross a threshold from enough heat for the muscles to be warm and not stiff to so much heat that there's not enough blood to the muscles because the body has to shunt a bunch to the skin to cool the body off.
