I'm not in the medical profession, but you should let your toe recover a bit more. You can work out your arms. Get some small weights and do a few reps of at least 3 reps. Once your toe is better start taking brisk walks and gradually build up from there. Leslie Sansone's Walk Away the Pounds is a good aerobic work out and it's not hard to do. With all exercises you can modify the moves and go at your own pace. My dad has diabetes and I know if I don't take care of myself now, I may end up a diabetic as well. I'm glad to know that you're taking the right steps now to battle diabetes.
