how much exercise to do on the treadmill
Walking is the key to good cardio treadmill workouts. For the first four weeks, you should try for twenty minutes of walking at a pace of about 4-8 mph, depending on your comfort level. Adding ten minutes for the stretching, warm-up and cool-down, youâll spend a half-hour each time. For the next five weeks of treadmill exercise, add ten minutes to your walking time. Do this until you are spending a total of sixty minutes on the treadmill at a time. To keep it interesting, you can change the incline slightly but adjust your speed accordingly to stay in that target heart rate range.
