What Muscles Get Worked When Walking on an Incline?

Whether you use a treadmill in the gym or climb a hill in the great outdoors, walking on an incline is a great low-impact cardio workout. It taxes not only your cardiovascular system but also several muscles throughout your lower body and even a few in your upper body.

The quadriceps is a group of four muscles -- the rectus femoris, vastus lateralis, vastus medialis and vastus intermedius -- that work together to extend the leg at the knee. When walking on an incline, your quadriceps work to straighten your leading leg as you bring the back one forward.


The biceps femoris, semitendinosus and semimembranosus make up the hamstring muscles on the back of the thigh. These muscles work together to extend the thigh and flex the knee. While you're walking on an incline, your hamstrings primarily work to extend the thigh on your leading leg as you move your back leg to the front.


The gluteus maximus works with the hamstrings to extend the thighs while you're walking on an incline. The greater the incline, the more your gluteus maximus and hamstrings must work. The gluteus medius and gluteus minimus work to stabilize the pelvis, preventing one side from sagging and thus allowing the swinging limb to clear the ground.

Lower Legs

You work all of the muscles of the lower legs when walking on an incline. The muscles on the front of the lower leg work together to lift your toes and the front of your foot off the ground as you bring your back leg to the front. You work the calf muscles on the back of the lower leg more intensely walking on an incline then when walking on a level surface. Your calves work as you push your foot away from the ground at the end of your stride.

Secondary Muscles

While walking is primarily a lower body exercise, you also work a few muscles on your upper body. You work your abdominal and back muscles constantly to keep your torso upright, especially as the incline increases. You work the muscles in your shoulders and upper arms as you perform the natural arm-swinging motion that accompanies walking.
