My question is: What needs to be changed or improved in the structure of human muscle fibers so that my genetically modified person can lift several tons ( from 700 to 3200 kilograms), taking into account the fact that this person weighs no more than 110-140 kilograms. That is, I need this Superman to have a huge, compared to ordinary people, physical strength.
To understand the limits of human physical capabilities, here are the best physical data of world athletes.
The record in the bench press in the bezekipirovachny division, today belongs to Kirill Sarych and is 335 kilograms (at a time).
The record in equipment belongs to Ryan Camely and is 486 kilograms.
The record of lifting the bar up over the head, with a push, belongs to Leonid Taranenko and is 267 kilograms.
In deadlift (lift above the ground), the record is about 500 kilograms.
Supplement: I need solutions related to biology. So no magic, Cybernetics, or exoskeletons. I ask about changes in the structure of the human body. In other words, what needs to be changed in the structure of the human body so that it has great physical strength, but at the same time looks like an ordinary person.
