After officially "receiving" Sadler as his coach, Sadler immediately started training Wang Lei impatiently.

But first, we need to do an individual test data sheet for Wang Lei.

Americans obviously attach great importance to this physical test data sheet. Whether it is athletes who play basketball or rugby, they must first test their physical fitness before joining a certain team, and the same is true for boxing athletes.

According to Sadler, make a physical test data sheet before training, and test it again every month later. Only in this way can we know whether Wang Lei's strength has improved and adjust the training plan accordingly.

Wang Lei didn't understand this very much, so he naturally followed Sadler's arrangements.

First, measure your height and wingspan, then measure your weight, and then test your bench press and squat strength, endurance, fat ratio, punching strength and movement speed, etc.

After a full hour and a half, Wang Lei completed the physical test.

His physical test data are as follows:

Height: 172cm

Arm-span: 175cm

Weight: 136 lbs

Fat ratio: 16%

Strength: 120 pounds and 28 times of bench press, 198 pounds of extreme strength; 200 pounds of squat 12 times of 305 pounds of extreme strength

Fist strength: 200 pounds for the left hand straight punch, 320 pounds for the right hand straight punch

Hundred meters speed: 10 seconds 85

Physical fitness: 3500 meters in 12 minutes

...

Looking at the physical test data on his hand, Sadler looked a little excited, but when Wang Lei asked him, he replied in a plain tone: "It's not bad, but the fat ratio is a little higher. As long as you strictly follow my training and dietary arrangements, I can reduce your fat ratio to less than 10% within three months, and your strength will increase by at least two-thirds."

"The strength is only increased by two-thirds?" Wang Lei was stunned.

"Don't think it's very rare. Your strength is now very good. A bench press of 136 pounds and a bench press of 198 pounds and a squat of 305 pounds is already close to the level of a first-class boxer. Raising another two-thirds is already the limit of your current weight. If you want to improve, you can only gain weight. But I don't recommend that you gain weight now, but you need to lose weight. It's best to lose weight to about 128 pounds within three months, and use a lightweight competition. After that, you will slowly increase your weight, increase one or two levels a year, and you will reach the heavyweight level in five years. Anyway, you are only sixteen years old now and are still growing up!"

After Sadler said that, he said with a solemn expression: "Professional boxing, the most popular level is always the heavyweight level, and only the heavyweight boxing champion is recognized as the strongest boxing champion in the world!"

Wang Lei agreed.

Think about boxing champion Ali and Mike Tyson at his peak. The former is so popular that almost everyone in the world knows him. The latter's appearance fee is tens of millions or 20 million US dollars, or even 30 million US dollars. Before Wang Lei's rebirth, although there was a light middleweight boxing champion nicknamed "Beautiful Boy" Floyd Mayweather's appearance fee broke Mike Tyson's record in 2012, in terms of fame, Mayweather is still far from boxing champion Ali and Mike Tyson, and is even incomparable.

If you don’t believe it, ask the Chinese, even if Chinese people who don’t know boxing almost know boxing champions Ali and Tyson, how many people know the “beautiful boy” Mayweather?

So Wang Lei agrees with Sadler's proposal.

Thinking of Mike Tyson, Wang Lei suddenly thought of George Foreman and asked curiously: "By the way, Sadler, I heard that Foreman's backhand punch is the heaviest among all heavyweight boxers. What is his boxing strength test score?"

Speaking of George Forman, Sadler's mouth twitched imperceptibly, but he replied: "In the 1970s, his left fist had a strength of 1,500 pounds and his right fist had a strength of 2,200 pounds!"

Wang Lei was shocked when he heard this: "2200 pounds, isn't that equivalent to one ton? How could it be so heavy? If such a heavy fist hits the head, then wouldn't it just knock off the head?"

"You are wrong!" But Sadler shook his head and said, "You forgot that forces interact with each other. It is two different things to hit the fixed boxing tester and hit someone. Because this involves the problem of "effective boxing force" and "depleting force". The 2200-pound boxing force sounds terrible. In theory, hitting the head will knock the head off, but in fact, people are not fixed boxing testers. Even if they stand there without dodging, their heads are hit by a 2200-pound fist, and the center of gravity will instantly be unbalanced and fall backwards. The 2200-pound boxing force will dissipate most of it, and eventually it will affect the opponent's brain.

The bag's fist strength may not exceed 1,000 pounds. If you keep moving in the ring, the force that acts on the opponent's body may still be dissipated. A master boxer who has certain experience in getting beaten and knows how to relieve force, such as Ali, will not be knocked down even if he gets hundreds of punches, because he can reduce the power of the 2,200 pounds of punch that hit him to less than 200 pounds. More importantly, in the case of continuous movement and fighting, the boxer may not be able to punch 2,200 pounds, which requires a good 'fist timing' to achieve."

After a pause, Sadler continued: "Only by seizing a good 'fist opportunity' can the boxer make a fatal heavy punch and apply more than 50% of the punch force to the opponent, he will be considered a 'heavy gunner'. Otherwise, even if he can shoot a 3,000-pound punch on the boxing force tester, he will not be able to defeat the opponent in the ring!"

Wang Lei was stunned when he heard this and felt it was very reasonable.

The reason is simple: if a person weighing 70 kilograms stands there casually, even if he doesn't move, a 2,000-pound fist will only knock him away and coma, but it will be difficult to kill him directly. It is even more impossible to break the cervical spine and knock his head off. But if the person stands firmly in a horse stance or lunge posture, or directly fixes his lower body, hitting his face with a 2,000-pound fist will definitely break the cervical spine and even directly knock off his head.

No wonder I saw many people on the Internet in my previous life saying that Tyson's fist was weighing 800 kilograms or even close to one ton, but it attracted countless people's suspicion.

The reason is that how can such a heavy fist not kill anyone?

The reason is that simple!

"Effective boxing power" and "depleting power" are theories that Wang Lei had never seen on the Internet in his previous life.

However, when it comes to "relieving force", Wang Lei thought of the "relieving force" mentioned by his grandfather in this life when he taught him boxing.

"Relieve power" is a common saying in Chinese martial arts or martial arts novels. It refers to the removal of the attack power acting on the body through clever body or muscle movements.

Mastering the skills of "relieving power" can easily resolve the enemy's heavy blow without getting hurt.

This "force-relieving" technique sounds similar to what Sadler said about the "force-relieving" theory.

It seems that whether it is Chinese martial arts or foreign boxing or fighting skills, the truth is the same in many aspects.

Wang Lei felt that it was necessary to ask his grandfather after he went back and ask him for the skills of "relieving his strength".

It seems that there are many techniques for Chinese martial arts that can be applied to boxing. You should try to integrate Chinese martial arts and boxing.

For example, the spiral force of Xingyiquan, the force-making skills of turning waves, and the "half-step collapse boxing" that the senior master Guo Yunshenquan fist has reached the flying man.

These techniques seem to be possible to integrate with boxing techniques!
