Exercise is a wonderful way of treating diabetes, and some people are able to treat their diabetes with a meal plan and exercise, and that's enough to keep their blood sugars in good control. Exercise will lower your blood sugar. It allows the sugar to go into the muscle cells, so your muscles have the energy they need in order to move and do what you need to do.
People feel better when they exercise.
It also will lower your blood pressure. And I think, Gina, you made a very good point. When we say exercise, you don't have to run a marathon. Just doing more activity than usual, parking your car further away from the grocery store, and walking up and down the stairs. Now, some of us as we get older, our knees have a little problem going up and down the stairs, but the more activity you can do and the recent president's report or the surgeon general's report on exercise said it isn't the amount of exercise you do at any one time but adding it up throughout the day.
