Use interval training to rev up your workout
Walk for the same amount of time at the same intensity day in and day out and your body will get as bored with your workout as you do. Throw in some variety with interval training, which involves changing the intensity of your workout throughout your exercise session. Every 5 minutes of your walk, jog for 1 minute. Every 5 minutes of your bike ride, shift into a higher gear and pedal hard for a minute. If you swim, speed up every other length. You’ll burn more calories in the same amount of time.
