However, most people who have diabetes should use light weights and lift them 12 to 15 times for each exercise, rather than lift heavy weights just a few times. Staying Safe Prevent injuries by warming up before exercise with 5 to 10 minutes of moderate activity and then stretching, and by cooling down slowly for 5 to 10 minutes after exercise. But you must take steps to regulate the process properly. Exercise 1 to 2 hours after a meal. Avoid exercise at times of peak insulin activity.
Morning exercise is ideal.
People who have type 1 diabetes should avoid evening exercise, if possible. Adjust your insulin dosage, if necessary. Patients who take oral antidiabetic drugs may need to change their dosages. Follow your doctor's advice. After prolonged or intense exercise, you may need extra carbohydrate foods for up to 24 hours to refill muscle starch reserves.
