@tjphillipp You must have a great pulmonary rehab facility in your town. I went for 13 sessions and quit. I hated it! Monitoring of O2 was not happening while exercising. The respiratory therapist said I wasn’t pushing myself hard enough. (I’m on 4L of oxygen 24/7) with severe emphysema) I had to go once a week to the education part of the rehab. That was horribly boring. The day I quit, I told the gal in charge, “I don’t have the time to come in here and watch a video of pulmonary rehab.” The video was a bunch of old people doing the exact same machines and exercises we were doing in our class. What was the sense of watching that? It was like sitting back and watching our class. Stupid. I am very active and I use a walking pad at home. I cannot stand the heat and humidity during our PA summers. Anyway, breathe easy and continued luck to you!
