Twist Rotation Over 180°C Pay attention to controlling the amplitude of the twist, the speed should be slow, the action should be gentle, otherwise there is also the risk of pulling the psoas muscle. Doctors recommend that the amplitude of the twist should not exceed 180°C, and frequency control is appropriate to complete one movement in 3-4 seconds. Unable to complete the pull-up but have to play the tractor The function of the upper limb retractor is similar to the traction treatment in the hospital. It is good for stretching the muscle and preventing the disc herniation. However, it is advisable that elderly people who do not have sufficient hand strength do not perform this exercise. To test their own hand strength, whether the pull-ups can be used as a standard, if an elderly person cannot even complete a pull-up, it is better to choose other stretching exercises. In addition, many elderly people like to use leg presses to exercise their flexibility, doctors advise, the best leg lift should not exceed the shoulder joints, otherwise it is easy to pull the hip ligaments and muscles. Spacewalker avoids excessive swinging Among many fitness equipment, spacewalkers are more popular and are loved by bodybuilders of all ages. Why is the spacewalker so popular? Because it is easy to use, it is easy to use, and it is effortless. It is also a pleasure to shake it off. But in fact, the spacewalk has a big drawback: it is easy to pull the psoas muscle. The doctor said that the spacewalker is actually very easy to pull the psoas muscle, especially the elderly muscles because of aging and reduced moisture, poor flexibility, if the legs swing too much, too fast, it is easy to pull the muscles around the spine . Therefore, it is advisable for the older people to swing their legs when doing a "spacewalk" at a frequency of about 45°C and a frequency of 3-4 seconds at a time. Pelvic softening syndrome for seniors This device is mainly used to exercise the lower limbs and waist strength, but for those elderly people who originally had hip osteomalacia, it is not suitable for this exercise. The so-called hip osteomalacia, the main symptom is often knee pain, and the stairs will feel powerless. In such old people, the function of weight bearing on the hip joint is not good. If you do another device, the knee extension muscles may be damaged, which may aggravate the original symptoms. Suffering from a disc herniation For people who work, or who are often prone to sedentary, psoas muscle or cervical muscle injury, Jiancang is a good choice. Because the fitness equipment, which allows the athlete to stretch the various joints of the body, it is a device that depends on the strength of both hands and feet to move up and down, stretching the entire body. One of the disadvantages of Jianji is that if the body condition of the bodybuilder has developed into a disc herniation, do not use this type of device because the spine absolutely cannot withstand the “frustration†of the rider.
