1. Wrong posture: If your posture is not correct, such as bending over or excessively bending your back, it will cause back pain. It is recommended to take some time to adjust the correct posture before running. You can consult a fitness instructor or consult the correct running posture tutorial.
2. Improper treadmill setting: If the treadmill is improperly set, such as the treadmill slope is too high or the speed is too fast, it will increase the burden on the back and cause pain. It is recommended to know the settings of the treadmill before running and make appropriate adjustments.
3. Insufficient or excessive exercise: If your exercise intensity is too small, your back muscles can't get enough exercise, resulting in pain. On the contrary, excessive exercise leads to muscle fatigue and strain. It is suggested to exercise moderately according to personal conditions, and pay attention to gradually increasing intensity and time, accompanied by static and dynamic stretching.
4. Soft tissue problems: When running, long-term impact and exercise may cause soft tissue injuries, such as muscle sprain or strain, and even disc herniation. It is suggested to warm up and stretch correctly before exercise to reduce the risk of injury. If there is pain, you need to seek medical attention in time.
In short, there may be many reasons for back pain after running on the treadmill. I suggest you check your posture and the setting of the treadmill, strengthen your exercise properly, and seek medical advice in time when you have pain.
