      B. Starting position: Both feet are open shoulder width, and the upper body front is parallel to the ground. The two knees drive the lower back muscles without tension. The palms of both hands are inward, the shoulders are the same width, and the arms are sagged and straight.
     C. Action process: Move the two upper arms to the sides, and lift the horizontal bar until the horizontal bar touches the upper abdomen and slowly lowers the reduction and repeats.
