Thanks Carol, do try to keep up the exercise, it is so good all round for everything, not just your heart! I struggled at first, out of breath and sore back and legs, feeling too tired to do it, but it is getting better each time I do it, it gets easier! Most times I would hit a wall on the return walk but of late I have not had this, the fitter you get, I think you will feel less tired! I have even started drinking water instead of my many cups of tea a day, this has got to help me I am sure!
I am also an asthmatic, for 17 years now, and have allergy problems, I am finding that going out walking regularly, has really helped my lung capacity, I just love taking in those big deep breaths of fresh air, something I have not always been able to do when my asthma is bad! So I can really vouch for the walking bit, my breathing is so much better for it!
