Exercise helps: Your blood pressure is slightly elevated but does not prevent you from exercising, in fact, you will see an improvement in your blood pressure if you are able to lose weight. You can monitor your blood pressure from time to time during your fitness program . If it does not improve or becomes higher then please see your doctor. Good luck on your weight loss journey!
