Why Does Treadmill Feel Harder?

Are you finding it harder to run on a treadmill than on a track or road? This is a common complaint among runners and can be frustrating. There are several reasons why a treadmill can feel harder, even if you’re running at the same speed and incline as you would outdoors. In this article, we’ll explore the reasons why this happens and what you can do about it.

1. Lack of Wind Resistance

When you run outdoors, you have to overcome wind resistance, which makes it harder to move forward. On a treadmill, there’s no wind resistance, so you don’t have to work as hard to move forward. This can make running on a treadmill feel easier than running outdoors. To simulate wind resistance on a treadmill, you can increase the incline or add resistance bands.

2. Monotonous Environment

Running on a treadmill can be boring, especially if you’re staring at a blank wall or watching the same TV show for the hundredth time. This can make your workout feel harder than it actually is. To make your treadmill workout more interesting, you can listen to music, podcasts, or audiobooks, or watch a movie or TV show that you’ve never seen before.

3. Lack of Variation

When you run outdoors, the terrain is constantly changing, which can make your workout more challenging. On a treadmill, the terrain is always the same, which can make your workout feel monotonous and boring. To add variation to your treadmill workout, you can vary the speed and incline, or try interval training.

4. Different Running Mechanics

Running on a treadmill requires a slightly different running form than running outdoors. On a treadmill, you don’t have to propel yourself forward as much, since the belt is doing some of the work for you. This can make your workout feel easier, but it can also lead to muscle imbalances and injuries. To avoid this, make sure you’re using proper running form on the treadmill.

5. Lack of Fresh Air

Running outdoors exposes you to fresh air, which can make your workout feel easier and more enjoyable. On a treadmill, the air can feel stale and stuffy, which can make your workout feel harder than it actually is. To simulate fresh air on a treadmill, you can open a window or use a fan.

6. Lack of Natural Scenery

Running outdoors exposes you to natural scenery, which can be calming and relaxing. On a treadmill, you’re staring at a blank wall or a TV screen, which can be stressful and distracting. To make your treadmill workout more calming and relaxing, you can try running in a scenic location on a virtual reality headset.

7. Lack of Vitamin D

Running outdoors exposes you to sunlight, which is a natural source of vitamin D. Vitamin D is important for bone health, immune function, and mood regulation. On a treadmill, you’re not exposed to sunlight, which can lead to vitamin D deficiency. To avoid this, make sure you’re getting enough vitamin D from other sources, such as food or supplements.

8. Different Surface

Running on a treadmill is different than running on a track or road, since the surface is softer and more cushioned. This can be easier on your joints, but it can also make your workout feel harder, since you’re not used to the different surface. To avoid this, make sure you’re wearing proper running shoes and gradually increase your mileage on the treadmill.

9. Different Temperature

Running outdoors exposes you to different temperatures, which can make your workout feel easier or harder depending on the weather. On a treadmill, the temperature is controlled, which can make your workout feel harder or easier depending on your body’s temperature regulation. To simulate outdoor temperatures on a treadmill, you can adjust the thermostat or wear more or less clothing.

10. Different Mental State

Running outdoors exposes you to different mental states, which can affect your workout. On a treadmill, you’re in a controlled environment, which can make your mental state more focused or distracted. To simulate outdoor mental states on a treadmill, you can practice mindfulness or visualization techniques.

In conclusion, there are several reasons why a treadmill can feel harder than running outdoors. By understanding these reasons and making adjustments to your treadmill workout, you can make your workout more enjoyable and effective. Remember to vary your speed and incline, use proper running form, and make your environment more interesting and comfortable. Happy running!

Frequently Asked Questions

Here are some of the frequently asked questions about why treadmill feels harder and the possible reasons behind it.

Why does the treadmill feel harder than running outside?

Many people feel that running on a treadmill is more challenging than running outside, even when covering the same distance. One possible reason for this is that the treadmill belt is moving beneath your feet, and you have to keep up with its pace. This can lead to a feeling of fatigue and exhaustion sooner than when running outside. Also, when running on a treadmill, you don’t have to fight against wind resistance or uneven terrain, and your body doesn’t have to adjust to the changing surfaces, which can make running outside feel easier.

Another reason why running on a treadmill can feel harder is due to the limited space and lack of natural scenery. When running outside, your mind can wander, and you can enjoy the fresh air and beautiful views. However, on a treadmill, you’re confined to a small space, which can make the experience feel monotonous and boring, leading to mental fatigue and exhaustion.

Why do my muscles tire faster on the treadmill?

Running on a treadmill can feel harder because it requires using the same muscles repeatedly without the variety of outdoor terrain. When running outside, your muscles have to adjust to uneven terrain, inclines, and declines, which can give them a break from repetitive stress. However, on a treadmill, your muscles have to work harder to maintain the same pace and movement, leading to faster fatigue and exhaustion.

Another reason why your muscles may tire faster on the treadmill is that you may be running at a higher speed or incline than you’re used to. If you’re not accustomed to the level of intensity, your muscles may tire faster, leading to a feeling of difficulty and exhaustion.

Why do I feel more breathless on the treadmill?

One reason why you may feel breathless on the treadmill is that the air circulation in the gym may not be as good as outside. When running outside, you have access to fresh air and natural ventilation, which can make breathing easier. However, on a treadmill, the air can feel stuffy and stale, leading to a feeling of breathlessness and fatigue.

Another reason why you may feel more breathless on the treadmill is that you may be running at a higher intensity than you’re used to. When running at a higher speed or incline, your heart and lungs have to work harder to supply oxygen to your muscles, leading to a feeling of breathlessness and exhaustion.

Why do I burn fewer calories on the treadmill?

One reason why you may burn fewer calories on the treadmill is that the machine does some of the work for you. When running outside, you have to work against wind resistance and uneven terrain, which can burn more calories. However, on a treadmill, the belt is moving beneath your feet, which can reduce the amount of energy you expend. Additionally, if you hold onto the rails or console, you reduce the amount of work your legs have to do, leading to fewer calories burned.

Another reason why you may burn fewer calories on the treadmill is that you’re not pushing yourself hard enough. If you’re not running at a high enough intensity, you may not burn as many calories as you would outside. To maximize calorie burn on the treadmill, try increasing the speed or incline or adding intervals of high-intensity exercise.

How can I make the treadmill feel easier?

One way to make the treadmill feel easier is to vary your workout. Instead of running at a steady pace, try intervals of high-intensity exercise followed by periods of rest. This can help you build endurance and prevent boredom and fatigue. Additionally, try incorporating music or podcasts into your workout to keep your mind engaged and distracted from the monotony of the treadmill.

Another way to make the treadmill feel easier is to focus on proper form and technique. Make sure your feet land under your body, your shoulders are relaxed, and your arms are swinging naturally. Also, try to maintain a consistent pace and avoid holding onto the rails or console, which can reduce the intensity of your workout. Finally, make sure to stay hydrated and fueled before and during your workout to prevent fatigue and exhaustion.
