1, neck discomfort, that is, when riding, the arm is too hard to support the weight of the body, and the muscles of the upper body are pulled hard to the neck and feel uncomfortable. So when riding, especially standing, you put more weight on your legs, and your arms only bear a little weight needed to maintain balance. 2. At the same time, don't bow your head too much when riding, which will not only cause neck discomfort, but also affect your breathing; But don't look up too much, which will also make your neck uncomfortable. Because most gymnasiums are now set up with coaches on the stage and members off the stage, this opportunity often leads members to look up at the coaches riding, which is easy to make their necks uncomfortable. A more reasonable design should be that the riding height of members is higher than that of coaches, so that members can naturally look down at coaches. 3, the waist is uncomfortable, and the height of the handlebar can be appropriately increased. The handlebar is too low, which will cause you to bend over and overstretch your waist muscles, which will lead to discomfort. You also need to adjust the front and rear position of the car seat correctly. Too far back of the car seat can also lead to excessive stretching of the back. 5. When riding, don't use what some coaches call hovering or hovering movements, as well as rigid riding movements. These actions will make your back muscles overuse and cause pain. 6. When riding, don't bow your back, and you can't bend your back like barbell practice, but show a natural physiological bend. When riding, keep your elbows slightly bent, don't push too hard, relax your neck naturally, and relax your back and waist. Excessive force on this part will cause discomfort when riding.
