The advantage of "walking backwards" is that the waist should be straight or slightly backward, so that the spine and back muscles will bear more gravity and exercise force than usual, so that the spine and back muscles that can not fully move when walking forward can be exercised, which is conducive to the smooth flow of blood. People who work or study at their desks all day can effectively eliminate fatigue and backache through this method. Research shows that middle-aged and elderly patients with chronic low back pain will feel comfortable and relaxed after walking backwards every time, and long-term persistence in doing it has obvious therapeutic effect on low back pain. Teenagers are in the period of growth and development, and walking backwards is also beneficial to trunk development and reduces the incidence of humpback in chicken breasts.
