Re: How soon would the effects of exercise show?
First of all, great job losing 40 pounds! Second of all, wonderful that you are making an effort to lose more.
Exercise will help you lose weight, and is good for your cardiovascular system, muscles, bones, mental health, etc........
But, it may not make much difference to your blood pressure. As Moxie75 says, sometimes its your genes, not environment. I've been exercising regularly for a year and I'm not sure its made much difference to my bp. But, along with the exercise I've changed my diet so that I've lost 18 pounds, and I'm working on 17 more, because I feel and look a lot better than I did.
