Description

Ligament stretching trainer for physical fitness

technical field

The utility model relates to the technical field of fitness equipment, in particular to a ligament stretching training device for physical fitness.

Background technique

Stretching exercise is a kind of fitness method. Stretching exercise can make the coordination between ligaments, muscles and joints more gentle, and reduce the possibility of injury, including active stretching and passive stretching. The so-called active stretching refers to mainly relying on the strength of contracting muscles, rather than other external forces to keep the movement in a specific position. The advantage is that it can increase the flexibility of movements and the strength of contracting muscles. The so-called passive stretching refers to using one's own body weight or equipment to keep the limbs in a certain stretched position. It is a slow and relaxing stretch, and it can also reduce the excitability of nerves and muscles. A great way to unwind after you're done.

Due to the long-term sedentary work of modern office workers, more and more people have problems with lumbar ligaments, such as lumbar muscle strain, lumbar disc herniation, etc. However, traditional exercise methods that rely on their own active stretching can easily lead to muscle and ligament pull. Injuries, and most of the traditional waist stretching devices are made of airtight rubber materials. After a long period of exercise, sweat will accumulate on the user's back and cause discomfort. Therefore, an auxiliary device suitable for stretching training of the waist ligaments is needed.
