Elliptical machine is different from other aerobic fitness equipment, and the trajectory of leg movement is also elliptical. When exercising, it feels like walking or running, which reduces the damage to the knees and is a popular fitness method for athletes. There are two kinds of elliptical machines, one can only do leg exercises, and the other requires you to use your hands and feet. These two kinds of fitness equipment are loved by many people. The latter is more challenging because it requires higher balance. In addition, the latter has a good exercise effect on the upper body and helps to increase the endurance of your arm. Elliptical machine, like all other fitness equipment, needs you to keep a good posture, pay attention to breathing and replenish enough water. Other precautions are: 1. Don't step back. Many people once thought that they could make good use of their hips when moving backwards on the elliptical machine, but in fact, both directions are mainly aimed at the thighs, and the pressure on the knee joint will increase when moving backwards, which will affect the knee joint for a long time. 2. Try not to let the soles of your feet leave the pedal. There are many moving parts on the elliptical machine. If your foot leaves the pedal, it may cause unnecessary injury and is not conducive to your balance. 3. Some elliptical machines can not only adjust the resistance, but also adjust the inclination, and try different angles, which is helpful to increase the interest.
