Flexibility of sitting posture is a test item used to reflect the flexibility of human body.

Sitting posture leaning forward practice

1. Stand forward: legs together, knees straight, upper body bent forward, palms touching the ground. Keep your upper body as close to your legs as possible, and continue to do it after recovering your posture (you can also put your hands on the back of your calf).

2. Cross: Put your hands on the ground in front of you, separate your legs into a straight line from left to right, and lie prone or roll your upper body.

3. Kicking: Stand up straight, raise your arms horizontally, take a small step forward with your left foot, straighten your right leg, lift your leg gently, kick your leg up quickly and forcefully, with a high height and a stable leg drop. Alternate movement of legs (difficult movement-feet flying in the air).

4. Jump in place: legs apart, knees bent, arms swinging backwards, in a semi-squatting position, jumping vertically upwards. At the same time, kick forward, bend your upper body forward, and stretch your arms forward to touch your feet (this action is similar to "starting from both ends").
