Breathing
Another bad habit when it comes to our breath? We’re working too hard to get in the oxygen that we need. Rather than taking deep, full breaths, we’re resorting to shallow, quick ones, forcing the body to work overtime to get the same amount of oxygen, Tamir says. This could partly be due to poor posture, most prevalent among those who slump over a screen all day (not to mention gym-goers who overemphasize mirror muscles instead of focusing on balance). With the shoulders hunched forward, we lose part of our ability to expand our diaphragm and take the big, full breaths that can boost workout perfomance, increase efficiency, and help manage stress.
