An incline challenges your backside.

An incline trainer and a treadmill look similar when they are positioned without an elevation. Both resemble a typical treadmill with a moving belt, a console and handrails. The biggest difference between the two machines is in the percentage value of the incline, or the decline, if the machine has that option.
Reach for the Stars
Although they resemble treadmills, incline trainers offer a more challenging workout since they incline to much greater percentages. The trainers elevate to 40 percent grades. This large hill climbing activates more muscle fibers in the glutes, calves and quadriceps and improves muscular endurance. The trainers also decline to greater degrees than treadmills. Some trainers decline to negative 6 percent, which improves muscle strengthening as you maintain your posture and balance.
Treadmills differ in inclines depending on the manufacturer and the purpose for which they are made. For example, commercial treadmills may incline higher than home models, but typically, treadmills elevate between zero and 10 or 15 percent. This resembles a gradually-sloping hill. You can incorporate hill training into your workout or alternate between hill and flat walking for an interval-style session.
One of the most popular benefits of adjusting the inclines on the exercise machines is that you burn more calories. Since you recruit a higher number of muscle fibers, your heart rate increases. The increase in pulse requires an increase in breathing rate to circulate oxygen to the working muscles. Oxygen changes fat into fuel for your exercise session and fat calories burned lead to weight loss.
Save the Knees
According to a study presented in "Gait and Posture" magazine, walking on an incline may have many benefits to the knees of the users. During the study, 15 males walked on a treadmill at five different inclines from 0 to 20 percent. At inclines greater than 5 percent, subject's knees show a reduction in internal rotation. This lessens the chances of cartilage degeneration, osteoarthritis and knee pain.
