The following workout involves changing your incline and speed throughout the workout to both burn more calories and make your gym workouts a little more interesting. You'll do four different cycles of 5-minute intervals. The first 5-minute interval includes increasing both speed and incline. In the second cycle you increase only your speed and the last two cycles will have you increasing the incline quite a bit, so get ready! The speeds/inclines given are suggestions only, so modify the workouts if you'd rather run more, walk more or make the workout shorter. Use the Perceived
Exertion Scale to determine how hard you're working. Check with your doctor before you start any exercise program.
