Chapter 2

After formally appointing Sadler as his coach, Sadler couldn't wait to start training Wang Lei. However, first, he needed to conduct a physical assessment for Wang Lei.

Americans clearly place great importance on physical assessment data. Whether it's basketball or football players, they all undergo physical tests before joining a team, and the same goes for boxers.

According to Sadler, conducting a physical assessment before training and then retesting every month helps to track Wang Lei's progress and adjust the training plan accordingly.

Wang Lei, not quite understanding, naturally followed Sadler's arrangements. They started with measuring his height and arm span, then his weight, followed by tests for bench press and squat strength, endurance, body fat ratio, punching power, and movement speed, among others...

After a full one and a half hours, Wang Lei finally completed the physical assessment. His results were as follows:

Height: 172 cm

Arm Span: 175 cm

Weight: 136 lbs

Body Fat Ratio: 16%

Strength: 28 reps of 120 lbs bench press, max strength 198 lbs; 12 reps of 200 lbs squat, max strength 305 lbs

Punching Power: Left straight punch 200 lbs, right straight punch 320 lbs

100m Speed: 10.85 seconds

Endurance: 3500 meters in 12 minutes

Looking at the physical assessment data, Sadler's expression was a bit excited. However, when Wang Lei asked him, he replied calmly, "Not bad, but your body fat ratio is a bit high. As long as you strictly follow my training and dietary arrangements, I can reduce your body fat ratio to below 10% within three months. At that time, your strength will increase by at least two-thirds."

"Only two-thirds?" Wang Lei was taken aback.

"Don't think it's a small amount. Your current strength is already excellent. With a weight of 136 lbs, you can bench press 198 lbs and squat 305 lbs, which is very close to the level of top boxers. Increasing by two-thirds is already your current weight's strength limit. To improve further, you need to gain weight. However, I don't recommend you gain weight now; instead, you should lose weight. Ideally, reduce your weight to around 128 lbs within three months to compete in the junior lightweight category. Then, you can gradually increase your weight, moving up one or two weight classes each year. In five years, you can reach the heavyweight category. After all, you're only sixteen and still growing!"

Sadler then added solemnly, "In professional boxing, the most popular and highest-profile category is always the heavyweight. Only the heavyweight champion is recognized as the world's strongest boxer!"

Wang Lei agreed. Thinking of Muhammad Ali and Mike Tyson in their prime, the former had an incredibly high popularity, known almost worldwide, while the latter's appearance fees often reached millions or tens of millions of dollars, even up to thirty million dollars. Before Wang Lei's rebirth, although the light middleweight champion, Floyd Mayweather, nicknamed "Pretty Boy," broke Tyson's record in 2012 with his appearance fee, in terms of fame, Mayweather was far behind Ali and Tyson, to the point of being incomparable.

If you ask the Chinese, even those who don't understand boxing almost all know Muhammad Ali and Tyson, but how many know "Pretty Boy" Mayweather?

Therefore, Wang Lei agreed with Sadler's suggestion. Thinking of Mike Tyson, Wang Lei suddenly thought of George Foreman and curiously asked, "By the way, Sadler, I heard that Foreman's right hook is the heaviest among all heavyweight boxers. What was his punching power test result?"

Mentioning George Foreman, Sadler's lips twitched slightly, but he still answered, "In the 1970 test, his left hook was 1500 lbs, and his right hook was 2200 lbs!"

Wang Lei was shocked, "2200 lbs, that's almost a ton? How can it be so heavy? If such a heavy punch hits someone's head, wouldn't it just knock the head off?"

"You're wrong!" Sadler shook his head and said, "You forgot that force is mutual. Hitting a stationary punching power tester and hitting a person are two different things. This involves 'effective punching power' and 'force dissipation.' A 2200 lbs punch sounds terrifying, and theoretically, it would knock someone's head off. However, a person is not a stationary punching power tester. Even if they stand still without dodging, when a 2200 lbs punch hits their head, their center of gravity will instantly lose balance and they will fall backward, dissipating most of the 2200 lbs of force. The actual force that hits the head would probably not exceed 1000 lbs. If the person is constantly moving, even more force would be dissipated. A skilled boxer with experience in force dissipation, like Ali, could take hundreds of punches without being knocked down because he can reduce the 2200 lbs of force to less than 200 lbs. More importantly, in a constantly moving fight, a boxer might not be able to deliver a 2200 lbs punch, which requires good 'punch timing.'"

Pausing for a moment, Sadler continued, "Only a boxer who can grasp good 'punch timing' can deliver a fatal heavy punch and apply more than 50% of the force to the opponent, qualifying as a 'heavy hitter.' Otherwise, even if they can deliver a 3000 lbs punch on a punching power tester, they won't be able to knock down an opponent in the ring!"

Wang Lei was taken aback but found it very reasonable.

The principle is simple: If a 70 kg person stands there casually, even if they don't move, a 2000 lbs punch to the face would only knock them out or send them flying, but it would be very difficult to kill them, let alone break their neck or knock their head off. However, if the person stands firmly in a horse stance or bow stance, or if their lower body is fixed, a 2000 lbs punch to the face would definitely break their neck, and might even knock their head off.

No wonder in his previous life, he saw many people online question the claim that Tyson's punch could weigh 800 kg or even close to a ton, as they doubted how such a heavy punch could not kill someone.

The reason is simple!

"Effective punching power" and "force dissipation" are theories Wang Lei had never seen before in his previous life.

However, when it came to "force dissipation," Wang Lei thought of the "force unloading" technique his grandfather taught him in this life.

"Force unloading" is a common term in martial arts or wuxia novels, referring to the skill of using clever body or muscle movements to dissipate the force of an attack.

Mastering "force unloading" allows one to easily neutralize heavy blows without injury.

This "force unloading" technique seems similar to the "force dissipation" theory Sadler mentioned.

It appears that whether it's martial arts or foreign boxing and combat sports, many principles are interconnected.

Wang Lei felt it was necessary to ask his grandfather about the "force unloading" technique when he returned.

It seems that many martial arts techniques can be applied to boxing, and he should try to integrate martial arts with boxing.

For example, the spiral force and wave force techniques from Xingyi Quan, and the "half-step punch" that sends opponents flying, as demonstrated by the master Guo Yunshen.

These techniques seem to have the potential to be integrated with boxing techniques!
