Your "online exercise forum" idea is certainly a good one! The one thing I know for certain is that I've gotten REALLY lazy about going for long walks as my primary means of exercising. My cell phone has an exercise tracker & I'd always feel encouraged when I would discover just how far I'd actually walked. Hopefully, our discussion has given me the encouragement to get back into the routine.
BTW .... just days ago I went to an exhibition and had to park FAR away from the venue. I even had to walk up 3 steep flights of stairs. I did it, but was definitely breathing hard by the time I got to the top! 😉 It was a pleasant/unpleasant reminder that I'd doing just fine for my age but DEFINITELY need to get back into exercising!! 🙂
