When sprinting, pay attention to the vertical alignment between the front knee and the toe, not exceeding the toe, and the throwing angle of the back foot should not be too large, generally not exceeding 45 degrees. In the picture below, the exerciser's forefoot knee exceeds the toe, and the hind foot is tilted too much, and the knee joint is easily injured.
When the footsteps move, the direction of the knees and toes should be consistent, and the internal and external combination should be combined when the formula is fixed, which conforms to the law of joint movement.
Non-professionals should not practice low-handedly. Because the steps are too big, the shelf is too low, and the weight of the knee joint increases, it is easy to cause knee joint injury. Beginners should start from the high boxing frame and gradually lower the boxing frame.
Knee joint is easy to be injured when rotating with load when bending, so when going up, you should sit back and leave your feet, shift your center of gravity to relax your waist and sink your hips, and use your waist and hips to drive your body to move.
The time for practicing Tai Ji Chuan should be well controlled, and the routine should not be too long. Too long practice time will increase the burden on the knee and cause knee joint injury. It is recommended to practice for about an hour every day.
