• Don’t begin an exercise program unless your diabetes is under control and you have discussed exercise safety with your physician. Because people with diabetes have an increased risk for heart disease, an exercise stress test may be recommended.
• Don’t exercise alone. Wear a bracelet that identifies you as someone with diabetes.
• If you take insulin or another medication, adjust the timing and amount of each dose as needed. Work with your physician and check your blood sugar level regularly so you can learn to balance your energy intake and output and your medication dosage.

• To prevent abnormally rapid absorption of injected insulin, inject it over a muscle that will not be exercised, and wait at least an hour before exercising.
• Check your blood sugar before, during, and after exercise. Adjust your diet and insulin dosage as needed. Keep high-carbohydrate foods on hand during a workout. Avoid exercise if your blood sugar level is above 250 mg/dl; if your blood sugar level is below 100 mg/dl, eat some carbohydrate-rich food before exercising.
• If you have poor circulation or numbness in your extremities, check your skin regularly for blisters and abrasions, especially on your feet. Avoid high-impact activities and wear comfortable shoes.
• For maximum benefit and minimum risk, choose moderate-intensity activities.
