Some thoughts...
- Posture, posture, Posture! Your mother was right. Keep your chest as straight and upright as you can, to ensure you are filling your lungs fully.
- Do things as you feel up to them, not based on an artificial schedule. This time around, mornings are better for me, so I walk then. Last time I had the surgery, I started feeling like walking around noon, so I went then.
- If you're not up to it, don't do it. That doesn't mean cop out. It just may mean to do less on that one day, or at a different time. Don't try to make up for each lost exercise. You have a lifetime for that.
- Stretch your limits with fully expanding your chest and being able to move (twist, turn) in all directions. This hurts a lot, so take it slowly. But if you want to be able do something, you'd better start getting back your capacity to do it. For example, I was finally able to expand my chest fully, at will, at eight days out (I'm nine days out now). Not my lungs - they were already fully expanded: this is about being able to fully "puff out" my chest, and regaining control of my rib cage, its flexibility, and the hundreds of timy, angry muscles within it (intercostals) and controlling it (pectorals).
- Be very careful movong yourself onto and off of beds, couches, etc. We automatically go to push with our hands, and that flexes the rib cage. If your sternum isn't healed (4-6 weeks), this can interfere with that process. Roll and leverage yourself out of bed, like you would with a bad backache.
- Other stuff works. Use your legs for strength moves. Your legs are fine (unless you donated a graft from there).
- Don't bend over to do things. If you have to put on shoes and socks, sit on the eged of the bed and bring your feet up to you instead, on at a time. Women: DO NOT PICK UP toys or laundry. Direct another family member to the offending materials, and have them pick them up ("Not later - now!").
