Open-close jumping is mainly divided into two parts: action 1, jumping in a standing position, feet spreading about 1.5 shoulder width, hands clapping to the top of the head, paying attention to keeping elbows as straight as possible and clamping them on both sides of the head, so that the body can stretch upward at the same time. Action 2: After jumping up again, put your feet together and clap your hands on both sides of your thighs. Pay attention to the fact that your body still extends to the top of your head and try not to hunch over. Repeat the action for one or two * * * for about thirty seconds. Opening and closing jump is a kind of whole body exercise, in which multiple joints can be mobilized to participate, thus generating more heat consumption. For jumping, it can help us to increase our heart rate quickly, thus improving our physical fitness and producing better fat burning effect. At the same time, jumping will also increase the muscle strength of our legs and exercise muscles to a certain extent, thus reducing muscle loss.

In fact, the opening jump can be very comprehensive and help to lose weight, but if you want to talk about the most important slimming parts, in fact, the most important thing is to focus on the positions of legs, arms, waist and abdomen. These three parts are the best slimming parts, because the effect and stimulation of these three parts participating in sports will be greater. Hands and feet must be the most involved in this sport, and the waist and abdomen should also maintain the stimulation and stability of the body during the exercise, so that they can also get great stimulation and exercise. This exercise is best done in the evening. In most cases, all aerobic exercises are suitable for evening. Just like running, jogging is one of the similar sports.
