Update: After having the weekend to rest, I went back into the gym today. Ran on the treadmill for the first time in 4 weeks. Had a little moment where I had to get my body back into the form, but it went pretty well. I think my cardiac capacity may have improved, but the drainage from sinuses and the weather are causing me some issues. The exercises involving my forearms were way stronger. My glutes and hams felt stronger running and my hand strength felt stronger doing pull-ups and cable rows. Overall, Id say the challenge was a great workout to switch things up and challenge your mental abilities to not give up. Until I get all the crap out of my lungs, I don't think I will feel the full result of the workout.
