What should I pay attention to when running on a customized manual treadmill without motor

There are some differences between running on a customized manual treadmill without motor and running on a normal road, because the difference between a treadmill and a road running is that the road on the former will move, while the road on the latter will not move. Road running uses the reaction force from the ground when landing, but the ground of the customized manual treadmill without motor is constantly moving backwards, instead of using the ground reaction to run, even if the posture is out of shape, you can continue to run.
Common wrong posture: When landing, the pelvis is not directly above the feet, that is, the waist sinks, and only runs below the knees. Once you change the wrong posture, it will increase the burden on your knees and waist when running on the road.

Therefore, when running on a customized manual treadmill without motor, you should pay more attention to your running posture. A few key points:
1. Don't accelerate too fast. The basic speed of general sports can be maintained at 8 km/h, and it can be adjusted to 9-12 km/h with a certain ability. Too fast will cause the body to lean forward and move backward continuously, increasing the burden on the knees and waist;
2. Face forward, don't look down;
3. Increase the swing range of the elbow backward, so that the shoulder blade can be moved;
4. For those who are just starting to run, there is no need to run a certain distance at a constant speed on a customized treadmill. If you feel that you can't run anymore, you can reduce your speed or even walk a certain distance. To complete the target distance is victory.
Another thing to note is that after each run on the customized manual treadmill without motor, do not stop immediately, let alone lie down or sit immediately. You have to slow down slowly and walk on a customized manual treadmill without motor for a few minutes to drop your heart rate below 120. After breathing is relaxed and normal, leave the treadmill and do a stretching exercise. Otherwise, you will suddenly stop running and get off the treadmill. In severe cases, you may faint.
