I'm not over the pneumonia yet, not by a long shot. But I'm breathing much more easily.
So I started back with light exercise today. Upper body weights, using the shoulder/arm muscles I keep getting tendonitis in. I did this because I really really need to keep those muscles in play now that they aren't hurting on a daily basis. I used the lightest weights I have, and not many reps, and only 3 sets.
Felt GREAT. But after a week on the couch ... it was absolutely all I could do without having to take breaks.
Maybe Friday I'll be able to do a moderate bike workout!
