Why wear high heels when you go to training? It's not a beauty contest! Wear a pair of warm clothes to guess it's true!
it's never cold in winter, but indoors, even if there is air conditioning, it's not necessarily warm. After all, it's not heating!
My parents lived there and said it was ok. There are two rooms and three rooms with a good environment.
As for clothes, it depends on your training for a long time. You must bring thick clothes. Practicality is king! Less belt is not enough to wear, and more belt is hard to take. Personally, I suggest taking more warm facilities!
