As an Ackerman, Mikasa’s physical abilities are insane. Seeing her throughout the series we see her carrying way more boxes and barrels than others and carrying multiple rails and thunder spears. It made me wonder how much can Mikasa lift? I would assume she carries 150+kg easily since she carries large bundles of thunder spears.
This thread by u/YamiRang ‘How much can Mikasa carry?‘ is very interesting because it calculates a higher amount that she can carry than I had assumed. It’s rather interesting so I suggest giving it a look! It’s always fun to read others’ theories and speculations.
