What Muscles Does the Treadmill Work?

A treadmill is known and used for getting your cardio workout in because not only does it get your heart rate up, but it also works your body muscles and tones them. People stick to walking or running on a treadmill according to their ease and preference. But what muscles does the treadmill work exactly?

Working out on a treadmill, such as walking and running, tones up our lower body muscles such as hamstrings, glutes, calves, and quadriceps. It not only tones them but also makes them strong and lean. The exertion caused by running on a treadmill exercises the cardiac muscles and keeps the heart in good shape.

If you want to know what muscles does the treadmill workout improve then our guide will be useful to you.

Muscle Sections Trained by the Treadmill

Our entire body is made up of various sorts and kinds of muscles, and each has its own respective purpose. Different types of muscles envelop our bones and provide them with flexibility and safety. Similarly, we have separate lower muscles that are engaged when we walk or do any physical exertion.

While working out on a treadmill, these muscles get active. The lower sections worked by the treadmill are:


These are the muscles located at the back of your thighs. When you run or walk on a treadmill, especially on an incline, they get worked up. This tones them up and provides them strength.

Usually, when people start working out or running, they feel a significant amount and level of pain in their hamstrings – the reason being the production of lactic acid. During workouts, our muscles need a constant supply of oxygen. The unavailability of oxygen spikes the production of lactic acid. Its accumulation causes muscle twitching or spasms.

Strong hamstrings assist athletes or people who are into fitness. Regularly working them out will increase your running stamina and make your workouts effective and enjoyable. You will not feel pain in your hamstrings if you work them out regularly as these muscles will gain endurance and become strong and firm.

Quadriceps is a large muscle group on the front part of your thigh extending to the knee. While running or walking, these muscles are engaged. The muscles of our body work in correlation.

The quads are engaged more effectively while walking on an incline at a slow speed in a backward direction. Your body’s quads are constantly working during physical activity and do most of the work while walking/running.

Muscle engagement of quadricep muscles while walking on the treadmill tones them as well as makes them firm and stiff. The fat collected around that region sheds off and builds up your muscle with the right diet.



Athletes or people who are really active in the field of sports and games know the significance of having strong calves. These muscles are located on the backside of your lower legs.

Athletes work on strengthening their calf muscles because they provide a firmer step while running or playing sports. Moreover, fitness junkies or those who generally work out a lot build up their calf muscles as it takes their workout game to a whole new level.

This can be done on a treadmill easily. Walking on an incline with your treadmill set at a slow setting works out the gastrocnemius muscle effectively, which in turn strengthens them if exercised on a regular basis.


Glutes or Gluteus Muscles

When you walk on an incline on a treadmill, direct emphasis and impact are placed on your glutes. Glutes are large muscles of your buttocks. It is composed of three more muscles which are Gluteus Maximus, Gluteus Medius, and Gluteus Minimus.

The biggest and the most prominent muscle of your butt is the Gluteus Maximus. The other two also have great significance in providing pelvic stability, which saves you from injuries and other damage while performing physical exercises.

While walking or running on the treadmill, these muscles are exercised. People who aim to build up their glute muscles take the help of a treadmill. Walking on an incline puts pressure on the lower backside, including the glutes.

You can easily achieve your aim of getting a toned and rounder butt through exercising on a treadmill. Many treadmill workout exercises, such as walking lunges and squats, can be performed while walking on a treadmill. But make sure to set your treadmill at a slow pace and hold the sidebars for a stronger grip and safety.



The most powerful organ of our body is the heart. It has the duty of pumping blood to every part of our body. The blood contains oxygen, which is important for respiration. Keeping the heart and the cardiovascular system healthy is extremely important for every human being. Mainly because of this purpose, many people take up exercising and working out.

People who do not work out or pump up their heart flow experience detriment in the long term. That is why many doctors advise walking and running regularly. This can be easily done at home or in the gym on a treadmill.

When you run or walk on a treadmill, your muscles start working and become more active. Therefore, they need more oxygen for respiration. This oxygen is provided by the blood, which is pumped from the heart. As the need for more oxygen increases, the blood supply also increases.

The pulse rate becomes more rapid as the heart works faster, and the heart muscles are exercised. The heart is made up of cardiac muscle, which is a striated flexible muscle composed of skeletal and smooth muscles in the upper body. This not only keeps the heart in good shape, but it also maintains its health, which is extremely important to keep up.



Cardio is one of the best ways to keep your heart rate up, which leads to a better and effective workout routine, and using a treadmill is not too difficult. To keep your body toned and your fat shredded, a treadmill is a great option. Both the lower and upper body muscles need to be kept active to stay in good shape and form.

Working out on a treadmill actively exercises the muscles of our lower body, such as the glutes, hamstrings, and calves. It also keeps the core engaged and works the cardiac muscles of our heart, keeping them strong and in good shape, while it helps to burn calories.

Therefore, if you aim to tone your body or to build up muscle mass, you can easily do it on a treadmill. With the right technique of using the treadmill, balanced diet, and by staying regular with your treadmill workouts, you can easily make sure to achieve your goals and aims. But the trick is consistency and patience.
