Why can't humans use muscle and tendons to fly?
The above question is not about flying. Flying is only an example for thoughts to go.
The major issue is the energy behind, which is the support of movements.
How can tandons and muscle produce force?
Are nerve system and blood the only sources to make them move?
May be more is needed.
Qi is the more important factor for "movements".
And its more than movements. Every part of the body, or even every cell of the parts need qi to activate them.
Any one can learn to use qi as a motivate source for their living needs.
And qi is more than an energy source.
Qi give you extra motivation and healing energy.
Qi is constantly circulating in the human body and once it is blocked will produce problem.
And the question is why can't humans fly?
If humans are given a pair of wings, do they need to have more extra Qi to fly?
Qi might be the more important issue in flying......
Or the flying of thoughts, too.
(I hope more people be involved to dream about the issue. It could be the next wave of invention,
And it could be more than a dream. It is possible to activate your own qi for your own usage: to work, to think and to heal. I used it very often. You will have a stronger mind and a stronger body.)
( The problem is how to activate your qi, it is not very difficult , because qi is related to mind, or thinking. You just summone, then it will come. and the qi flow can be guided by your will. )

note:
Here is a standard answer from the traditional knowledge of an AI machine which may be a hindrance of new thoughts, if it is trusted completely.
Humans can't use muscles and tendons to fly primarily because our bodies are not anatomically or physiologically designed for flight. Several key reasons explain this:
Lack of Suitable Wing Structures:
Humans do not have wings or any appendages capable of generating the necessary lift. Bird wings are specialized structures with a large surface area, lightweight bones, and specific muscle arrangements that allow for powerful, sustained flapping or gliding—features humans lack.
Insufficient Muscle Power and Structure:
Bird flight relies on highly efficient, large pectoral muscles attached to a lightweight skeleton. Human muscles are not adapted for the rapid, repetitive, and forceful wing flapping motions needed for flight. Our muscle mass and attachment points are optimized for bipedal locomotion, not for generating lift.
Body Mass and Bone Density:
Human bodies are relatively heavy and dense compared to flying animals like birds and bats, which have lightweight bones and bodies optimized for flight. The human skeleton is designed to support upright walking and running, not to minimize weight for flight.
Energy Requirements:
Flying is energy-intensive. Birds have high metabolic rates and specialized respiratory systems to support sustained flight. Humans would need an enormous amount of energy and a highly efficient oxygen delivery system to sustain flight, which our physiology does not support.
Evolutionary Constraints:
Human evolution has prioritized other traits—such as dexterity, intelligence, and endurance running—over flight. The development of wings and the associated musculature would require a fundamental redesign of our anatomy and physiology, which evolution has not favored.
In summary:
While humans can mimic flight through technology (airplanes, gliders, jetpacks), our muscles and tendons alone are not capable of producing the necessary lift and thrust for flight because of anatomical, physiological, and evolutionary limitations.
