I’m excited to say that I started my workout again! Its been soo long and you know once you stop its extremely hard to start back up again. I’m hoping to possess enough endurance to make it a permanent part of my routine, if not everyday at least a few days a week. I really do not want to stop again, picking it back up is the worst! So anyway, about breathing.
OK so you know how when you’re exercising you get tired really fast? One thing I’ve noticed that helps me, and maybe it will help you too, is to always remember to breathe. It sounds simple but you’ll be amazed how we forget this when caught up in the moment. You see, when I get overwhelmed with a routine its mostly because I need to catch my breath. I know some of you may be thinking, “But I do breathe!” No, not like that. When I say breathe I mean breath out. Exhale and get a rhythm going. Instead of breathing regularly and trying to catch your breath, breathe to the beat. When I exhale at the end of the beat, letting all of the air out of my abs, I find myself being able to endure much longer than when I breathe normally. And by normal I mean without control. Controlling my breathing was the difference between doing twenty minutes yesterday and thirty minutes today.
