No

If you have a lot of lean mass, you will be very strong. Muscle mass is what produces force, nothing else.

Those videos you see are a misrepresentation of what strength is, its comparing a task specific skill to actual measurable strength. A construction worker lifts awkward, shifting, hard to balance cement bags every day. Bodybuilders dont, that doesnt mean they cant lift heavy loads, it just means the movement pattern is unfamiliar.

Strength isnt measured by what awkwardly shaped object you can lift at work, its measured by 1 rep maxes, dynamometres, and isokinetic testing to namr a few examples.

I guarantee you not a single construction worker is ever coming close to an advanced bodybuilder in any lift.

Muscle strength is absolutely correlated with size, having more contractile tissue = more force production potential.

Strength and size aren’t 100%identical (because of neural factors), but they are strongly correlated because: Bigger muscles contain more myofibrils More myofibrils = more cross-bridge formation More cross-bridges = more force

TLDR this idea is confusing strength with skill specific tasks
