I have two exercises I do that target specific muscles. I've added them to my regular routine as I find they're a weak point in my overall strength. One helps fight a back injury from a car accident, the other helps stability when trail running. Neither muscles get used enough in anything else I do to really develop, but their lack of strength can occasionally be an issue for me. I've found it beneficial. To be clear, I'm by no means ripped, just trying to be more active.
