Exercise is just one thing you can do to control your weight.  Are there specific exercises you should do?  Not really.  Choose any cardio exercise (walking, running, cycling, aerobics classes, skating, tennis, etc.)--anything that raises your heart rate.  Lifting weights is a critical component of an effective weight loss program since muscle burns more calories than fat.  You don't have to train like Arnold to get solid, strong muscles.  Just 2-3 days a week for 30 minutes or so is enough.  Your doctor can help you with weight loss resources or you can go the expert route and hire a personal trainer.  Make sure your trainer has education and experience in working with diabetics.  To get started on your exercise program, start at the Beginner's Corner or head over to the Workout Center for ideas for your workouts.

The circuit training workout is comprised of two circuits, each with six strength/cardio exercises that are completed one right after the other, with little or no rest in between.  You'll do each exercise for a specified amount of time (or as long as you can safely do so) and then move on to the next exercise.  Once you complete all exercises, that is considered one circuit.  Make sure you warm up with 5-10 minutes of light cardio and cool down with a stretch.  Times are suggestion only--please modify according to your fitness level and perceived exertion.
