During his game, in the heat and the smog, Charlesworth leaned on his stick and then
squatted to capture a moment's
breath whenever the action paused.
Also, in order to reap the benefits of wearing a weightlifting belt, you have to breathe properly
during heavy lifts — for example, when
squatting, take a deep
breath just before you descend and hold it until you reach the lowest point of the
squat, then perform what is known as the Valsava maneuver (the technique you would use when trying to clear your ears with the help of exhaling) or forcefully exhaling against a closed airway.
