Well Christmas day was day 40 and I had every intention of working out before the extended family festivities began, however, once I started playing with the twins and their toys, I soon lost that one and only half hour window to myself so I skipped the workout. I'll tell ya, transforming Optimus Prime into a semi-truck certainly wasn't much easier than my workout! Why do they make it so difficult?
I got back on the wagon December 26 and 27 with a 32 minute workout on the elliptical machine. Today I did some spot checks on my HR and pulse ox. I was surprised that with 3 Liters of oxygen I was still sating at 93% with a HR of 170. I slowed it down a bit to get the HR under control, but the sats remained at 93. I thought maybe the oximeter was wrong. So I took the oxygen off and my sats immediately dropped to 90. So at least the o2 was helping.
