2, leg exercise: the walking function of the leg is weakening day by day, of course, the flexibility is getting worse and worse. People who like sports can ensure that the leg muscles are beautiful and strong, and will not easily become "elephant legs". The first is to relax the quadriceps femoris in the front leg. The left hand stands upright on a support point, and the right hand pulls the right ankle backwards, so that the right thigh is vertical to the ground, the heel is close to the hip, and the left leg is straight. Hold this position for more than 25 seconds, and then switch legs.
3, arm and shoulder movement: the simplest shoulder movement is around the shoulder joint, as long as there is a little space, you can take the opportunity to do it several times. This slightly more difficult movement requires the body to be straight, the arms to be straight behind the body, the palms to be open, the hands to be closed, and the wrists to be rotated, so that the fingertips are upward, the arms are attached to the back, and the palms are slowly extended upward, and stop after reaching the limit 15 seconds.
