I was born with feet in the 1st percentile of the population and they stayed that way even despite getting taller. Now every shoe shopping experience is awkward af.

It’s totally true from a physics standpoint. A longer lever arm between the load and fulcrum requires more force to move the same weight, all else being equal. Edit: thinking on this more, I think a type 3 lever is more applicable to my chest flye example, but the same concept applies; as you lengthen the load arm relative to the effort arm, more input force is required to move a given load.
“Harder to exercise” is poorly defined, especially when you go on to discuss endurance, speed, and force, all of which are very different terms.
I totally get what you’re saying, but I specifically narrowed it down to force for a reason. My shorter friends kick my ass in lifting due to the mechanical advantage their shorter limbs have, but I smoke them in a distance run because my longer limbs allow me to traverse a greater distance in a single step. This is complicated though because larger lungs are a factor here too.
“All else being equal,” it’s not equal though, that’s what I’m saying. Our legs have electrical and muscular aids in them which make them unlike a lever completely.
You shortened it down to simplify a complex topic. I’m pointing out it’s not that simple and it’s okay to learn more. As we age we should keep up with learning dense subjects to keep up our neuroplastocity, and it’s a social virtue. Right now I’ve been learning about electrobiochemistry for instance. You can just download textbooks. Please stop committing to simplicity when reality is complex.
Physiology wouldn’t encapsulate a huge subject and multiple specialty fields (physiologists, occupational therapists, physical therapists, medical technologists, physical educators, surgeons, biomedical engineers) if it was simple physics. We wouldn’t need all the other muscles and junk if it was all simple physics. It’s not. It’s a highly complicated series of biochemical, magnetic, electrical, energetic, and physical properties that work against and with each other
