Correct Breathing

Correct breathing is a prerequisite to proper training. Inhale deeply before starting on any exercise.
Exhale in a controlled manner during the most strenuous part of the exercise. During the easier part of the exercise, you inhale again.
In other words, you exhale when making the greatest effort whilst you inhale on the way back to the point where you started from. It is that simple! Try to do the exercises strictly as prescribed whilst inhaling and exhaling evenly. In this way you will teach yourself to breathe correctly during exercising.

Correct breathing will ensure that oxygen will be transported evenly from the lungs to the muscles.
