调整雪橇机的座椅，使膝盖成45度角。 坐在雪橇机上，背部靠在靠背上，双脚与肩同宽放在踏板上。 握住座椅两侧的把手以保持稳定性。 伸展双腿，将脚踏板推离身体，脚后跟保持在脚踏板上。 在完全伸展的位置暂停片刻。 慢慢弯曲膝盖，将踏板放回到身体的方向，控制动作。 重复所需的重复次数。
Adjust the seat of the sled machine so that your knees are at a 45-degree angle. Sit on the sled machine with your back against the backrest and your feet shoulder-width apart on the footplate. Grip the handles on the sides of the seat for stability. Push the footplate away from your body by extending your legs, keeping your heels on the footplate. Pause for a moment at the fully extended position. Slowly bend your knees and lower the footplate back towards your body, controlling the movement. Repeat for the desired number of repetitions.
