将雪橇机的座椅和脚踏板调整到舒适的位置。 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。 继续推动，直到双腿几乎完全伸展，但不要锁住膝盖。 在动作的最高点暂停片刻，然后弯曲膝盖，慢慢地将踏板放回到身体的方向。 重复所需的重复次数。
Adjust the seat and footplate of the sled machine to a comfortable position. 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. Continue pushing until your legs are almost fully extended, but without locking your knees. Pause for a moment at the top of the movement, then slowly lower the footplate back towards your body by bending your knees. Repeat for the desired number of repetitions.
