Why do stronger legs go up first and weaker legs go down first?
When we go up the stairs, we shift our weight to the leg that is stepping on the step, and rely on this leg to support and drive the whole body up, so we need to step on the step with a stronger leg first. When going down the stairs, our center of gravity will be on the back leg, so we should take the relatively weak leg first.
Why don't the center of gravity tilt forward?
When going up and down stairs, the further forward the person's center of gravity, the greater the pressure on the knee joint. Over time, greater knee pressure can cause knee cartilage to wear down, inflammation of soft tissues, and pain.
Why step the entire ball of your foot smoothly on the steps?
When the entire sole of the foot is stable, we can use the back foot to press the ground. When the ball of the hindfoot presses the ground, it activates the gluteal muscles. In this way, when going up and down the stairs, the body can be moved with the strength of the glutes, thereby relieving the pressure on the knee joint.
Why should the knees be forward, avoiding the inside and outside figure-eight feet?
Inward knee or figure-eight feet may increase pressure on the inside, lateral and ankle joints of the knee joint, increasing the risk of joint injury during the journey up and down stairs.
