I'm gonna take a wild guess and assume this is a Russian fitness or workout thread, since it's in Cyrillic. To be honest, I'm not really sure what a "мультитренажер" is, but I'd love it if someone could translate for us English-speaking folks
lol, not sure what "Мультитренажер своими руками за 7 дней" means, but I'm assuming you want to know how to make a home gym in 7 days? If so, it's doable, but it depends on how complex you want it to be. Can you give us more context on what you're looking for?
