Biohacking?

I am not sure if what I am setting out to do is technically called "biohacking". Most of what I have seen written on the subject of biohacking seems to say it refers to "a hobbyist who experiments with DNA and other aspects of genetics (Wikipedia)." I want to tweak my biochemistry in order to reach my fitness goals, and because I want to see just how much control I can have over this meat suit and to what level. The subject has begun to fascinate me. If anybody has any thoughts on whether or not I can really call this biohacking please comment.
