On a same mass basis, people who “struggle” or “stiffen” are oddly much easier to lift or carry than people who “relax” or “let go”, and i cannot understand why.
In: Biology
When you lift someone you aren’t only using muscles to move them upward, you’re also using muscles to keep them from moving side to side.
Someone engaging their muscles to become rigid doesn’t move side to side as much, whereas someone flopping around forces you to “stabilize” them which requires concentrated effort and therefore requires strength + energy.
