The jumping rope is a tool for exercising as well as playing in many different ways. The rope should be used in a manner that one has to jump and allow it to be passed under the feet and over the head. Let’s understand more about this tool from the information below. The effects of jumping rope exercises are similar to others like jogging and cycling. Calories burned using the jumping rope can go up to as high as 700 in a single hour. If the calories burned per jump are to be calculated, it accounts for 0.1. The activity of running a mile in eight minutes is therefore equal to performing the jumping rope exercise for 10 minutes. There is an advantage of jumping rope exercises over jogging or running exercise: compared with the process of jumping, damage caused to the knees while running is greater. So, one can conclude that the use of jumping rope to lose weight should be preferred to other exercises. Basic Jumping : The basic jumping rope technique is that of lifting both feet at the same time while keeping a little distance between them. Let us look at the different jumping rope techniques in the following paragraphs. Criss-cross Jumping: This form of jumping rope technique is similar to that of the basic method. Arms get crossed while performing this jump. The right hand moves towards the left side of the body and vice versa（反之亦然）. Double Under: In the double under technique, the height of a jump is greater than that in basic jumping. Since the jump is higher, there is more time to swing the rope. This time is used for swinging the rope twice. The move is therefore, referred to as double under. Front-back Cross: The front-back cross technique is similar to that of criss-cross. In which both arms cross each other. In the front-back cross, however, one of the arms is crossed behind the back. The jumping rope is a simple tool used for performing exercises. There are many benefits offered by the jump rope workouts. The jumping rope is not costly and easy to carry. T
