Do you disagree that it's useful to distinguish between strength and endurance?
codingdave asserted, "I think legs that can carry a 50 pound pack to the top of a mountain are "stronger" than a guy who can lift twice as much as me, but can't even run a 5K."
The former is an example of great endurance (without necessarily having great strength), and the latter is an example of great strength without endurance. You can have one without the other, so they're different, and it's plainly incorrect to say that a person with high endurance/low strength is "stronger" than a person with high strength/low endurance.
