Because boxing takes one hour and 450 calories, while boxing takes about one minute, and one calorie is 4 joules. 450 * 4/60 = 1, 875 joules. Each individual is different, and the number of muscle fibers, nerve recruitment ability, weight, bone density, subcutaneous fat and height are different, and the strength that can be exerted is also different.

The damage force comes from the kinetic energy carried by the object itself, and the unit is Joule. Kinetic energy = 1/2 mv squared, m is the mass, and v is the speed. Constant mass, double speed, increase lethality several times, while constant speed, double mass, only double kinetic energy.

Speed depends on muscle relaxation and contraction, as well as strength technology and strength framework. Only when the body is relaxed can the speed be achieved, and the speed is doubled. How much force you exert on an object, the object will rebound to give you the same reaction force, and the body shape will have a complete body frame, thus absorbing the reaction force.

The benefits of boxing:

1, self-defense. In the news, we often see the news that girls are hurt. Through boxing sparring training, you can naturally learn self-defense methods and understand self-defense consciousness.

2. You can improve your reaction ability. People's reaction ability can be gradually improved in training. Learn boxing, because you should always pay attention to each other's movements and be highly concentrated. Slowly, your reaction ability and physical sensitivity will be greatly improved.

3. vent your emotions. In work and life, there will always be things that go wrong. In boxing, all negative emotions can be vented, that is, all the pressure can be played out.
