So you are saying that mgik is different that physical force? Or that magic can help physical force?, as you say it, a character may simple focus his "life energy" into his fist to shatter somebody nuts like a glass vase. But it can't do the same without using magic unless he has trained his body for it. (Which would be a very weird training if it only consist on shattering nuts...)

And, although i can't relate to most of the examples, i can slightly relate to Dragon Ball, and, as far as i remember, they seem to punch hard even when throwing giant ki balls everywhere and chewing the scenery.
%Also, i think i was talking about the Celestia lifting 100 tons, but it doesnt matter...~%
