Treadmills provide a convenient way to exercise in a fitness club or at home rather than outdoors. Most of the newer treadmills include an incline option that creates an uphill climbing effect to make your workout more challenging. The treadmill incline option can be adjusted to varying grades that usually peak at 10 to 12 percent. The deep breathing that occurs when you move uphill as you exercise may expand the strength of your lungs by increasing blood flow. Hiking uphill at a moderate, steady pace is also an excellent way to increase endurance and improve muscle strength, especially in the lower half of the body.
Cardio & Muscle Building
The cardiovascular effects of the treadmill are known to strengthen your heart when you work out consistently. But treadmills can also strengthen and tone muscles, particularly when the machine is set at an incline. Treadmills can be set to automatically increase and decrease the incline level for a workout, simulating the effects of walking or running up and down hills. The specific levels can be adjusted to accommodate your fitness level and to challenge you to improve your conditioning including muscle tone and development. The incline setting can be especially beneficial to your leg muscles.
Calf Muscles
Incline training will more quickly and effectively work to strengthen your leg muscles than walking or running on a level surface. The uphill positioning works to stretch your calves and help build long, lean calf muscles.
You will get maximum benefits from the treadmill's incline feature by releasing your hands from the handle bars and allowing your arms to swing as they would if you were walking up a hill outdoors.
Thigh & Buttocks Muscles
The treadmill's incline feature also helps build strength in your ankles, thighs (quadriceps) and buttocks (gluteal muscles). The steeper the incline is set, the greater the benefit. As your legs become stronger, you can continue to challenge yourself by increasing the incline setting.
