Sincerely, this kind of pull-up action can't be done by ordinary people for hundreds of times.

Many people who claim to do dozens of pull-ups at a time are actually not doing standard exercises at all. They won't fall to the lowest point, and they won't put the next Bala up. Sometimes they swing back and forth to help, sometimes they can't pull up, so they try their best to stretch their necks. These are all actions that make you pull up and get twice the result with half the effort. Finally, it is meaningless for people who want to exercise just for the number that no one recognizes and can only comfort themselves.

Therefore, I also suggest that the subject should take standard movements as the first priority when exercising and practicing pull-ups, rather than blindly pursuing quantity.

Many gymnasts only do thirty or forty standard pull-ups at a time. Ordinary people can't do 400 pull-ups a day without a few years' practice.

Then, let's talk about whether pull-ups are useful for self-defense. Let's just say that having a good body and a strong body is definitely good for self-defense. As for how useful it is, it is hard to say that it is particularly great.

The best way to defend yourself is to avoid conflict from the beginning, instead of getting involved, and then use your "ability" to solve each other.

Of course, I know you are not satisfied with this statement, but putting this sentence in the first place is to remind all fitness enthusiasts that no matter what they learn, they should first remember that they are still human, and don't take the initiative to make trouble if nothing happens.

If you start to practice pull-ups, at first, you will feel that your physical fitness, strength, endurance and other physical qualities are growing rapidly, but before long, your muscles will grow slowly. After practicing for a long time, it seems that I can't make one more than before. This time is actually to remind you that you should try other sports. At this time, maybe you need to go to the gym and do some targeted training for different parts of your body, and then

So it can be said that doing pull-ups can definitely increase muscles and strength, but you can't expect to improve forever just by doing pull-ups.

In particular, I think if the subject wants to improve his self-defense ability, he can learn Sanda or Muay Thai, a practical martial art, and then use pull-ups to keep fit. I think promotion will be faster. I hope what I said is helpful to you.

First of all, let's talk about the rationality of 400 pull-ups every day. Any exercise has a bottleneck. Normal people usually start to have a bottleneck when doing standard pull-ups, which is generally around 10- 13. Judging from the height and weight, it is not surprising that some people have bottlenecks after 18. Then, if the subject is a beginner who hasn't even broken through the bottleneck once, it is quite dangerous to do forty or fifty groups in ten groups of eight, and muscle dissolution is likely to occur, which is life-threatening. If the subjects can do about 25 pull-ups in one breath after breaking the bottleneck once, or 35 pull-ups after breaking the bottleneck twice, or 60 pull-ups after practicing swing pull-ups, there is no problem in doing a group of 400 pull-ups continuously.

Then there are muscles and strength. Whether it's doing standards or surfing, it has a great effect on strength training. If you practice surfing, compared with the standard pull-ups, your explosive power will be stronger, the coordination of your waist, abdomen, shoulders and back will be better, and the muscles of your arms and shoulders will be stretched wider, but the muscles will certainly not increase too much, far from reaching the standard effect.

Finally, self-defense, if you break through the bottleneck twice and can do 30 standards or 60 waves in one breath, you can crush ordinary people of the same height and weight. Basically, you can lift and throw a person with the same weight with one hand, or you can double the weight of your fallen opponent.

However, in any case, just practicing pull-ups doesn't mean you can play, let alone compete with the same people who have practiced. You will win in prison and lose in the ward, that's for sure.

You want to pass this training of smelling chickens and dancing

Gain: the dual function of muscle and strength, as well as self-defense.

Say it one by one.

About muscle and strength:

It should be elaborated in the training stage.

At the beginning of training, you can gain some muscles and strength.

Because of your training intensity, it is already relatively high in the field of unarmed.

In the first few months of retraining, your muscles and strength will advance by leaps and bounds.

However, there will be an upper limit to this development.

When your muscles adapt to pull-ups and your weight

Your explosive power will stop growing.

If you continue to practice, it will only increase your endurance.

Besides, because of your intensive training day after day.

Maybe you will face the problem of muscle strain.

So please reduce the training frequency.

Let's talk about self-defense:

Your pull-ups

Have the training of latissimus dorsi, biceps and forearm muscles.

And these parts happen to be an important source of human attack power.

Therefore, after long-term training, your boxing strength has really improved.

In the face of unarmed bad guys without training foundation, you have room for self-defense.

But the bad guys are not stupid. Most of them are prepared or strong.

Therefore, please don't regard pull-ups as Dharma Yijin Sutra.

The best training for self-defense: long-distance running.

I hope it helps you.

400? Are you sure? Are you bragging? You may not be able to do it after practicing for half an hour, but it's still not standard. Beginners should practice slowly. Too fucking tired. Absolutely exceeding the standard! Your body can't stand it, your muscles should be fine, but self-defense is really useless, my personal opinion.

I believe he can make 400, because when I was 48 years old, I made eight groups in groups of ten every morning. If it continues in the afternoon, 200 on the same day is still ok. This can exercise the strength and endurance of the whole body. As for whether to gain muscle, I said it depends on what the goal is! If you want to achieve the aesthetic feeling of muscle enlargement, you may be disappointed!
