Void, those are great quotes! No doubt people train hard. I'm looking back in time and saying--was it necessary for me to train that hard? Or was it just the result of my own aggressive view of what was necessary?
You've reminded me of common theme in Daoist literature called "The Dao of the left, and the Dao of the right." Scholars sometimes style this an anti-Buddhist doctrine because it goes: The Dao of the left is short, and the effects are immediate. The Dao of the right is the long road of suffering --sometimes requiring multiple lives. But both the Dao of the Right and the Dao of the Left lead to the same place eventually. I guess Cheng Man Ching was an advocate of suffering, the dao of the right. I'm not. But I'm not judging it either, that one way to go.

Thanks for the great arguments. My expert (he runs a lab) on muscle chemistry tells me we are really at the beginning of understanding muscles, not at the end. Just an aside: I was short on money in my early 20's and I answered a call for medical experiments at the San Francisco VA, $60 for an hour. They were testing just what you described. They put me in an MRI device with a weighted pedal for me to push on with my leg. Then they charted the chemistry of maximum effort, peak performance and fatigue and then recovery after fatigue. They loved me as a test subject and invited me back for a second round because none of their other test subjects were willing to push their muscles as hard as I was. I was crazy.
I like the idea that perhaps the difference between internally trained muscles and externally trained muscles is that the internally trained ones have better access to oxygen. Internally trained muscles have more qi, perhaps we should just call qi: oxygen? Time for some more tests!
So OK, lets say that there are two types of muscle quality...strength and endurance (I think there are more actually). Why would internal martial artists prefer (assuming they do) endurance types of muscle?
You're probably right about the skinny guys carrying people up the mountain, It's like backpacking for 2 weeks.
I'm only asking the kids to demonstrate upward force against 150lbs for about 5 inches in a short burst. And that is enough for fighting purposes--throws and punches rarely need more than 5 inches of upward force from the moment of contact. Kids can do that and so can most adults without any training.
There is a heck of a lot more to training than what we are talking about here, and your argument about endurance is worth pondering. The idea I'm challenging is that we need MORE strength than what we already have naturally.
I don't think the video of Wu Qiuting I linked too shows a guy with big muscles...But If you think he does have big muscles I'm worried that others on this forum will look at my quads and think they are strong too. But I assure you I wear two pairs of long underwear, I don't think most people seeing my legs would think they look muscular by American standards, but perhaps martial artists would see some development. None of that negates the fact that I try not to let my muscle get bigger.
