So not everyone should run out and do this immediately, lol. Boxers and wrestlers apparently use this strategy to lose some water weight in a pinch. For whatever reasons, I think these are kinda hot to watch : )
I've got a pantry load of them, they're good for food scraps and empty bottles.
It makes sense doing that but I'd hate to do it. All that sweat pooling around your ankles. I've seen guys run in summer in full zipped up tracksuits. It's kinda similar to the yoga you can do in the sauna.
I'd rather the guy in the second clip not put the suit on hehe
