I was without Internet access a few days, so I’m behind on my updates.
On Tuesday I had limited time at the gym. I hit the elliptical for about 15 minutes with the mask at the highest setting. Here’s a photo of my stats.

I had another short workout yesterday (Wednesday). I did about 20 minutes on the elliptical with the mask on high. I didn’t get a good photo of the machine.
After that, I went to Krav. Mike and I had one student, so we trained with her. I got a nice workout. After class, I worked security at a bar until midnight – it wasn’t much of a workout. I just got some steps in.
Today was a rest day.
