What Muscles Does the Treadmill Work On?

The treadmill is a great way to work on your leg muscles, especially your quads (the large muscles on the front of your thighs). When you walk or run on an incline, you also work your glutes (butt) and hamstrings (back of your thigh). If you add hand weights to your routine, you can also work your arms. Treadmills are a great way to get a full-body workout!

Muscle Group Worked by Treadmill

Treadmills are mostly used for lower-body exercises such as walking, running, and jogging. However, they can also be used for upper-body muscles by holding on to the handrails. This equipment works multiple muscle groups in your body, including the following:

The muscles in our body are organized into different groups, and each group is connected to a specific joint. The muscles surround the bones and assist in the movement of that joint to which they belong. When we exercise, our muscles must work. For example, when we walk, run, or perform physical activity on the lower part of our body, our muscles below are employed. The core is also engaged when walking or running on an incline mode treadmill. Also, don’t forget about the boneless one, the cardiac muscle, which is the most essential since it’s responsible for keeping our hearts beating. Walking, jogging, running, or interval training are the best physical activities based on physical strength, need, or ability.

Let’s take a look at the muscles that are activated while working out on a treadmill:


These are the muscles located at the back of your thighs. This is made of three muscles- the biceps femoris, semitendinosus, and semimembranosus. These muscles are responsible for hip extension and knee flexion.

The hamstrings assist athletes and people who participate in sports by providing additional power to their muscles. Exercising your hamstrings regularly will improve your running endurance and make your activities more efficient and fun. Exercising your hamstrings daily won’t feel any discomfort since these muscles will grow stronger and harder over time.

Answer to What Muscles Does a Treadmill Work


Quadriceps are a large muscle group on your thigh extending to the knee. It comprises four muscles- the rectus femoris, vastus medialis, vastus lateralis, and intermedius. All of these muscles are responsible for knee extension.

The quadriceps help in walking, jogging, climbing stairs, and lifting objects. These muscles also provide power to your legs when you kick a ball or jump. If you exercise your quadriceps regularly, you will improve your leg strength and reduce the risk of knee injuries. While running or walking, these muscles are certainly engaged too.

Walking on an incline slowly in a backward direction engages your quads more effectively. During exercise, your body’s quads continuously work and do most of the work when you walk or run.

Walking on the treadmill activates the quadriceps and makes them firm and hard. With the correct diet, the fat that collects there will dissolve away and be absorbed by your muscle.


This is a significant muscle group for athletes and sports enthusiasts. They understand the importance of having calf strengths. The gastrocnemius and soleus muscles make up this group from knee to ankle.

The calf muscles are very important in our day-to-day activities. For example, the muscles in our calf help us push off the ground and move forward when we walk or run. If you exercise your calves regularly, you will improve your leg strength and reduce the risk. Athletes focus on tightening their calf muscles and enhancing their stride when running or playing sports. Furthermore, fitness freaks, and people who exercise regularly build up their calf muscles as it takes their workout to a new level.

This is straightforward on a treadmill. Walking on an incline with your treadmill set at a low speed activates the gastrocnemius muscle, which improves them if done regularly.

Glutes or Gluteus Muscles

When you walk up an incline on a treadmill, your glutes are emphasized and hit. Your glutes are made up of four muscles: Gluteus Maximus, Medius, Minimus, and Maximus.

Treadmills engage muscles are engaged when you walk or run on them. A treadmill is required for those who want to build up their glute muscles. Walking on an incline puts pressure on the lower back, including the glutes, so carefully choosing your walking route is important.

Treadmills are ideal for toning and rounding your behind, as they allow you to work out in a low-impact manner. Walking lunges and squats can be done while walking on a treadmill, which is good since many muscle groups may be targeted. However, be careful to adjust the speed of your treadmill to a slow pace and grasp.

Core Muscles

Your core muscles include your abs and your obliques. They are critical to maintaining a trim, attractive physique. They maintain your body’s stability and equilibrium while also protecting the spine. Who doesn’t want a strong, flat core? And the good news is that a treadmill can help you get there!

When you walk or run on a treadmill, your core muscles are activated, keeping you upright and stabilizing your pelvis. Your transverse abdominal muscle also strains to force air from your lungs as your breathing quickens.

These muscles are worked harder due to the greater effort you put into your treadmill exercise, especially if you run on an elevated slope.

You can do a few things to make your core workout more effective on a treadmill: Stand upright with your shoulders, back and head up; this allows your core muscles to function effectively by keeping everything straight.

Breathe deeply:

Engaging your core while breathing through your nose and out through your mouth will contract your abs. Your core muscles will function as a result of this.
