Bi Fang shook his head: "Unfortunately, the ratio of muscle fibers in each muscle of each person has been determined since birth. Fast-twitch muscles and slow-twitch muscles will not transform into each other due to training, so everyone's potential

It’s also different.”

"Some people's tendon connection points are further away from the joints, which naturally results in greater strength. The moment arms of their muscles are longer, because torque = force * moment arm."

"You may never be Alex Honnold, but you can be a better version of yourself."

There were more and more people gathering around, and the more Bi Fang talked, the more his heart sank.

With so many people, can you really go out after you finish speaking?

But now, Bi Fang can only bite the bullet and continue.

"When you do an action, not all muscle fibers are involved. If you don't need to do an action with all your strength, then your most powerful fast-twitch muscles are just watching."

"And when you exert all your strength to suck milk, even though you can no longer hold on, your slow-twitch muscles haven't started to feel good yet, and your brain will intelligently control to use only the minimum number of muscle fibers to complete the action.

"

"The tension in the muscle fibers of each movement ranges from the slowest slow-twitch muscles to the fastest fast-twitch muscles."

"This is also why bouldering improves strength faster than climbing the route. When climbing the route, even though you are so tired that you can't even grasp the big points, you actually don't use your powerful fast-twitch muscles.

"

Yao Jun yawned under the tree.

Compared to Bifang, he is much less well-known. Although he is often called a profiteer and reviled, not many people really know what he looks like.

Nine p.m.

Yao Jun, who was watching dramas in the office, received a call from Bi Fang.

"Where are the people, come here quickly, I'm out!"

"Ha, it's out? It's earlier than I thought."

"Hurry up, I'm exhausted. This thing is more tiring than live streaming."

"Hahaha, come right away."

It was already half past nine when Bi Fang saw the Gambia rat.

Dozens of mice live together, and the scene is quite spectacular. Especially these mice, each one is as big as a kitten, and they look even more exaggerated, as if they have arrived in some strange country.

Seeing Bi Fang and Yao Jun coming over, these rats were not afraid of strangers at all. When they saw Bi Fang spreading his palms to reveal pieces of bread, more than half of the rats gathered around them, scrambling to grab the food and stuffing their cheeks with it.

It's full and bulging, and it looks like a squirrel.

Bi Fang explained to Yao Jun while feeding and returning the food.

"This kind of rat is larger than ordinary rats and has a more sensitive sense of smell. At the earliest, the Venezuelan military cultivated several qualified demining rats through artificial breeding and selective breeding, so that the rats could smell the

The smell of gunpowder is used to determine whether there are hidden mines, and the reward is only a piece of banana."

"An efficient demining rat can detect tens of thousands of square meters of land in one day."

Yao Jun shrugged: "Anyway, I'm not interested in mice. It's your money that I spent. I don't care. What are you going to do? Take them all back? Or pick two? Keep the others here?"

"Pick two, and keep the rest here so they can interact with tourists."

Bi Fang looked carefully and finally focused on a Gambian rat lying in front of a glass display case.

Behind the glass is a venomous snake curled up and hanging upside down on a branch.

The two sides faced off for a long time, and the venomous snake suddenly reached out to attack, but ended up hitting the glass with its head, making a muffled sound.

What is surprising is that the Gambia rat behind the glass showed no sign of being frightened at all. It even just moved its body slightly, and then moved closer to observe it carefully.

"That's it."

Bi Fang's interest greatly increased and he set his goal.

After living for a long time, animals are not surprised to be aware of the existence of glass, but after the poisonous snake on the other side of the glass attacks, they are not afraid at all.

In this case, people may be frightened, let alone a mouse, which shows that it is not only smart, but also very courageous.

This is what Bi Fang needs.

It was too easy to encounter dangerous situations in the wilderness, and he didn't want a Gambia rat that would be so frightened and run away like crazy when it encountered danger that it could never be found afterwards.

"There are really more and more animals in the house."

Bi Fang sighed.
