( Breathing: Breathing is very important when performing lifts especially for the beginner and when lifting heavy weights. It fills you with oxygen at the right moment and helps you to complete the exercise using proper form.
The general "rule" to follow when it comes to breathing and weightlifting is to breath in when in the negative phase of the lift , and breath out when extending the most effort in lifting the weight.
This is especially important when performing heavy compound movements such as the squat, breathing out at the right moment when you are attempting to bring the weight "up" again can in fact help you to complete the rep. )
