Treadmill is a common fitness equipment, which can be used for jogging or brisk walking. However, when using the treadmill to walk fast, sometimes there will be backache, which may be caused by the following reasons.

First of all, when using the treadmill to walk fast, the body posture is incorrect, which easily leads to backache. When walking fast, you should keep your body upright, your shoulders droop naturally and your neck relax, otherwise it will cause a certain burden on your waist.

Secondly, muscle fatigue may also lead to backache. When walking fast on the treadmill, if the time is too long or the intensity is too large, it will lead to muscle fatigue, especially the muscles at the waist, which will lead to backache.

Thirdly, insufficient warm-up is also one of the reasons for backache. When walking fast on the treadmill, you must fully warm up, including stretching and relaxing, to help your body gradually adapt to the state of exercise.

Finally, the wrong insole may also lead to backache. The choice of sports shoes is very important. If the insole is too hard or inappropriate, it will affect the blood circulation of the feet, leading to backache.

In short, there are many reasons for backache when using the treadmill, which need to be treated according to your own situation. Adjusting your posture properly, fully warming up, and choosing the right sports shoes are all helpful to relieve backache. At the same time, we should also pay attention to avoid excessive fatigue during exercise and avoid long-term weight-bearing exercise, so as not to cause greater harm to the body.
