When sitting cross-legged, the legs are bent and crossed respectively, the ankle joint of the left leg is placed at the knee joint of the right leg, and the body leans forward to maintain the posture. If you can't insist on 10 minutes, it means that your legs, ankles and hips are not flexible enough, and you usually lack flexibility exercises.
It only takes about 5 minutes to stretch the waist, hips and legs at a time, which can greatly improve the flexibility of the body and easily complete cross-legged sitting.
Sitting forward: Sit on the mat or bed, straighten your legs together, lean forward as far as possible, touch your calves and shins with your hands, hold 15-30 seconds when you feel the back of your thighs tightened, rest for half a minute, and then do another group. In order to increase the interest and test your progress, you can try to move your hand forward in each exercise until your hand is beyond your feet and your chest can be attached to your knees.
Kneeling posture extension: Kneel on the mat, knees together, ankles extended backward, so that feet stick to the mat. Then put your hands back, lean your upper body back as far as possible, and hold it for 15-30 seconds when you feel the front part of your thigh tightened. Take a break for half a minute and do another group. With the increase of leg flexibility, you will be able to make your upper body lie on the mat.
