The Olympians use blood flow restriction training as a muscle building method in preparation for the Tokyo Olympics.

As Insider reported, this technique involves wrapping the limbs to restrict blood flow to the muscles.

Blood flow restriction is not only meant to build muscle without lifting very heavy weights, but also to increase endurance and recovery.

The New York Times reported Athletes such as swimmer Michael Andrew, 22, and distance runner Galen Rupp, 35, both used this method before games.

According to the Times, Andrew wore “tourniquets” on his arms and legs in a training pool in Tokyo, while Rupp tied his legs with straps.

Andrew said he swims with limited blood flow in his arms and tries to keep up with the times he usually swims.

“Obviously, this is very difficult,” Andrew told the Times.

“But you are imitating the feeling of real pain that makes the body grow again.”

He said he also uses bracelets before races and to aid recovery.

The blood flow restriction training was invented by a man named Yoshiaki Sato in Japan, where it is known as KAATSU.

“It’s very useful for post-injury training that doesn’t allow for heavier loads,” personal trainer Harry Smith previously told The Independent.

“Blood flow restriction training forces you to use much lighter loads than usual, as limited venous return traps blood in the muscle, limiting some of its range of motion and causing a huge buildup of metabolites and

lactic acid
… “

Smith said that if you are not injured and can exercise normally, blood restriction is the best way to achieve results over time.
