My dad was a machinist, apprenticed in Germany after WW2. Always somewhat overweight (5'9", 225 lbs during his "peak" years), but he could lift guys up by their belt with one arm, and pick up and move 200+ lb metal billets when he got too impatient to wheel the crane over. Even at 85 now, he's probably stronger in his arms than most 60 year olds. But I'm also not saying ALL of his co-workers were that strong, either.
Takes mass to move mass. Most of the strongest people in the world look "fat" and usually have a hefty gut. Strong and jacked are orthogonal characteristics.
I know what you mean, but from a physics perspective, no, it just takes force to move mass. More mass will generate more downward force due to gravity, and more force in other directions due to momentum once it’s moving, but there’s more to generating force than just mass. I’m not a kinesiologist but I would think how much force muscles generate depends on the amount and size of the fibers (mass) but also on their contractive efficiency and the amount of energy they can obtain and employ to contract (not necessarily proportional to mass, involves cardiovascular fitness)
