This might help your Cardio
Cardio can get overwhelming, especially if we get to the point of huffing and puffing and needing to catch our breath. It's not a bad thing, especially if you are just starting out or juat getting back into exercise. How I overcame this issue is by breathing through just my nose for at least the first half of my cardio session. I call this pure nasal breathing. Why would this work? It's pretty simple. You start training your body to use oxygen more efficiently. Learning to do this will also help you recover faster after your session. If you are only starting with just 10-20 minutes of cardio, just do cardio at a pace that is still challenging, yet allows you to breath just through your nose for the first half, then finish as you normally would. Over time, you can use this technique for 60%, then 75%, then eventually 100% of your cardio session.
