Breathing strategies for resistance training

Have you ever focused on how you breathe during exercise? For some people, it's the last thing that comes to mind, especially when lifting weights. But is there a best practice for breathing while resistance training? There are many strategies out there, some that even involve not breathing (Valsalva maneuver). The goal of breathing (or not breathing) is to increase intra-thoracic pressure (pressure around the spine) to best maintain posture & technique during the movement. With that, pressure around your heart & throughout the cardiovascular system will be affected. You may have even noticed feeling light-headed or left with a headache post workout. I bet your breathing may be the culprit. So, tune in for some of my best breathing strategies for resistance training, as well as a way to improve your breathing in general.
