I have been using a stationary bike and I connect my pump to the Magazine holder. I can easily see my blood sugars while I bike for 45 min. 13.8 It is very helpful tracking your workouts. Sometimes my liver dumps, I then can give myself a unit to prevent my sugars from going to 300 or I can see if I need sugar before I get too low. I don’t have to stop until my sugars get up. I hate to stop because of low or high sugars. It just reminds me of my stupid disease.!!!
