Why Does My Face Get Red During Workouts?

Most likey its the the training hall itself. Dose it have A-C? Is the floor carpet, padded, or hard surface? Any windows or fans? A small room with lots of bodies in it?

Or it could be that you are just so excited to be doing what you have dreamed about doing your whole life.
