Struggle In Whole Life
God has given man a body so that he can carry out physical tasks in his daily life as well as procreate so that new human beings can continually enter this test of life. If you have figured that bodybuilding is useless then you can choose not to do it. There are many uses of your body that are still very valid. Many things can be used in various different ways, some of which might not be of any use to us. We have been granted the faculties of reason and rationality to figure out how best we can use those things and what uses we can do away with.
