Nothing too taxing, but it was HOT in the tiny fitness center.
For the treadmill, I set it up for a slow climb (5mph, 5% grade). around the 20 minute mark, my HR started to push past 145, so I dropped the incline to 2.5%, then back to 3% for the rest of the 30 minutes. After that, I took a couple minutes and set myself up on the cross trainer. I did a random program which seemed to just slowly ramp up the intensity over the 30 minutes.
I have to admit I felt a lot better this morning than I have in a couple weeks, so maybe I am finally shaking this bug.
