I started seriously dieting and exercising again 91 days ago. At the time my resting heart rate was about 85, which was not so great. This morning my resting heart rate is 68, which is much better. It's much easier for me to catch my breath after walking now as well. When I started three months ago I'd be breathing hard for five minutes, but now it's more like a minute or two. I've still got plenty of gut, but it's much easier to lug it around now.
