Spacewalker is a kind of fitness equipment popular with the elderly. The operation is simple and labor-saving, and swinging back and forth is very enjoyable. However, the device is easy to strain the lumbar muscles, and it is not suitable for the elderly to swing too much when walking in space.

Waist twister is also one of the favorite fitness equipment for the elderly. When using the waist twisting device, the elderly should pay attention to controlling the waist twisting angle. The waist twisting speed should be slow and the movement should be gentle, otherwise there is a danger of pulling back muscles.

The function of upper limb traction fitness equipment is similar to going to the hospital for traction treatment, which is beneficial to stretching muscles and preventing disc herniation. But for those elderly people who are not strong enough, it is best not to do this exercise, but to use other stretching equipment to exercise.

Cycling machine is very suitable for people who often sit at their desks for a long time, and it can also relieve some old people from neck muscle and waist muscle strain. But for those elderly people with herniated intervertebral discs, don't use this kind of equipment for exercise, because the spine can't stand the "tossing" of riding machines.
