Breathing / getting the proper amount of oxygen is critical to any cardio workout. We all know that!

But, do we really know how to maximize / optimize each and every breath.

I have experimented with different types of breathing techniques and have found a couple to be very useful.

I refer to one as the 888 Breathing and the other as the 2 & 2 Breathing techniques. Check them out, give them a try and see if they work for you.
