How to get pumped up right before a game
Take a few minutes to breathe.
If you are nervous before the game, take a second to breathe. Start by closing your eyes and focusing on your breathing.

Select from:
a). Then, take a few deep breaths from your diaphragm. If you don't have a diaphragm, close your eyes and clear your mind to focus on breathing through each nostril.
b). Count to two in your mind as you inhale through your nose. Hold your breathe there for one second then exhale through your nose for two seconds.
c). How you breathe will depend upon personal preferences. Some people are more confident with their breathing, and other people tend to feel more relaxed throughout the game, and find it more flattering if they are doing it instead of dreading it.
d). Just focusing on the muscles in your chest is better. Relaxation techniques for low pressure breathing should engage each part of your body.
The answer is:
b).
