As we know from health experts today; exercising is a very important part of healthy living. Since the disciples of Jesus and for instance St. Paul and the Old Testament prophets had nothing good to say about it; why is such an important part of living and good health completely absent from the Bible? In fact the word ‘exercise’ is mentioned as more less derogatory.
I do not regard the Old Testament as an example of good holy scripture. It's very confusing, often because of the translation problems you already mentioned. But it also seems to praise extremely brutal actions, which is weird, maybe it's all a metaphor. Probably. But very confusing objectively.
The New Testament, right, I don't remember much about exercise, except that Jesus and the disciples were walking all the time to different places, so actually exercise was an inherent part of life back then; there were no machines, everything was done by human labor, so there was no need to exercise, except for athletes, gladiators, soldiers and so on.
I don't know about other scriptures praising physical exercise, except the writings of Yogananda.
