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.
This study suggests that being adequately hydrated before and
during weight
lifting is very important for a proper hormonal and metabolic response to resistance exercise — in other words, if you are dehydrated before and
during a weight
lifting session, you won't able to build muscle and burn fat like you would if you were
properly hydrated.
