How might one exercise when you're anemic?

Treat the anemia...: It's important first to determine the cause of anemia. The most common type, especially in young women, is iron-deficiency, often from heavy menstrual cycles or inadequate iron consumption in the diet. Then, focus on correcting the anemia. You typically can exercise as much as your symptoms allow (if approved by md), but endurance athletes often have reduced capacity until the anemia is corrected.
