Elliptical machine is a kind of machine which adopts the theory of human factors engineering and is very suitable for sports. Its advantage is that the load on all joints of the body is particularly small. As we all know, swimming is the most advocated sport now, because in water, on the one hand, there is resistance, on the other hand, there is buoyancy. The advantage is that it can increase the load when you exercise, and at the same time, it will not increase the load on the joints of the body and will not cause harm to the joints and synovium of the body. Secondly, good exercise is running. Both of them have aerobic exercise. Swimming and running are all full-body exercises, and all parts of the body participate in them, so they are very good exercises. Running is the second sport after swimming, and there is no space restriction. It's convenient to run if you want. The appearance of elliptical machine has added a transitional exercise between swimming and running, that is, elliptical machine is also a whole-body exercise and an aerobic exercise, but it is second only to swimming. Because of the uneven resistance, only the leg resistance is large. Compared with running, the load on the body is much smaller. Therefore, it has become the second best aerobic exercise after swimming. I still push hard, but the disadvantage is that the machine takes up a lot of space. After a long time, the parts are worn and the sound is loud. I still think elliptical machine is better than treadmill, which may be my personal preference. I haven't used a treadmill, and I dare not say what it is like. My friend runs on the treadmill, but he says it's not very good. Now she is going to sell it. She has changed to running outdoors, but she doesn't need it now.

I think no matter which one you choose, you must stick to it. The important thing is to persevere.
