You need to watch your diet also. I teach spinning and cross fit and I have seen a reverse in many cases of some of my clients that were in really bad shape before taking my classes. Blood sugar dropped, blood pressure back to normal and they are are more active and full of energy now. Some of them are over age 70 close to 80 and in great shape now.
Good luck will pray for you and hope you will take care of yourself.
Exercise is good for BP?
