Going to the Max

The other day, I did my treadmill routine -- elevation steadily at 6 and then a pump up to 10 with a step down of elevation for each minute. Woohoo!

An added benefit to feeling great and sweating like crazy was my VO2max. That is maximum oxygen uptake, and I spent 4 minutes and 28 seconds in this zone. That's hard to do. And I was heaving. My heart rate monitor displayed my ticker chiming in the 160s and 170s -- 170s! That's high. And I was. I could feel this level of oxygen.

Spending time in this zone is critical. A weekly target is how I try to achieve it -- small amounts spread across the week of exercises. I don't always get it done, but it sure does feel great when I do.

I love going to the max.
