I'm slowly starting to exercise again. I can't believe how out of shape I am. My neighborhood is very hilly, steep hills, Three days ago I went around the block and up the huge hill. I was wheezing and had to stop for a second. Two days ago, I walked slower, but went around without wheezing. Yesterday I was really out of breath, but not terribly so, and today I was out of breath but caught it very quickly. I always hate the beginning of trying to get back into shape
