strange back

[kdynamite]

hey guys, just needed some ideas on how to get tyson's lower back, i have the upper back pretty much taken care of but i haven't seen too many people with a lower back like this... if you ever notice any of his fights in his prime, his back muscles go all the way down and round off to the middle of his back...this is the best picture i could find..
