The duck walk is an exercise for athletes. The duck walk is done with the hands behind the back, in a deep crouch, with both feet withdrawn, and the upper body is not allowed to rise and fall during the walk.
The advantage of duck walk is that it helps to practice calf strength in soccer. But the disadvantage of this training method is that if the leg strength is not enough then there will be damage to the waist and knee muscles, it is recommended that the beginning of the stage do not practice too much ground. The general troops rarely have such training, but in some individual troops, out of the will to cultivate the requirements, there will be such a training method.
