This culture is full of blood and rust.

Aspiring male prisoners give up their manual addiction to improve bench press data, and they also eat the world's stinkiest canned tuna.

Before 1990s, American prisons allowed the allocation of fitness equipment in public sports areas.

Later, the prison was strengthened and these guys were confiscated.

In Georgia alone, the weight of fitness equipment recovered from prisons reaches 150 tons.

In the process of developing their own fitness equipment, the new generation of prisoners not only exercised their muscles, but also developed their IQ. Making heavy objects is the most common choice.

The prisoner with unknown information uploaded a video of the exercise in the pipeline.

A large number of netizens expressed satisfaction with his craftsmanship.

Some China netizens left a message after the video saying:

"He just finished his work in prison, and so many fitness instructors outside the prison are unemployed."

According to the relevant laws of the United States, it is a crime to install any form of fitness equipment in American prisons.

Therefore, in keeping with DIY tradition, prisoners have begun to make simple fitness equipment by hand.
