[Dragon Ball (All)] How exactly does ki work?

From what I understand, using ki means drawing out of your own life force, or soul. So if someone is enhanced to super strength levels, such as any of the SSJs, what is ki doing? Enhancing their muscles? Making them bulkier? Muscles only have so much tensile strength so how could they lift up something incredibly heavier than a muscle should be able to lift?

Projecting ki is essentially using your life force to cause physical change in the world. Maybe it's an explosion, maybe it's moving your body through the air, whatever.

In this case, ki is strengthening/supporting your muscles and bones. An easy way to think about it is that the muscles lift as much as they can, and the ki lifts the rest.
