On Monday and Tuesday I continued with my elliptical routine. Things seemed normal. HR starts at 130-ish and ends with an average of 150. The sats are great w/ 2 liters of o2. They never dip below 95 unless I sprint for a minute or two. I might go down to 1 liter and see if it makes a difference.
I didn't work out today, day 61. I had a dentist appointment all morning. I may sneak in a workout this afternoon, but don't hold your breath. I feel like I'm entitled to a day or two off each week!
