im 24 yrs old. 6ft ' 170 lbs. n i absolutely hate the way my ribcage is so narrow... i dont know how i can make it look better... i think my torso is genetically extra long and it makes it really hard for me to fix it. i dont know what to do... is there anything i can do to build muscle around my torso to make it look any better.. or am i just screwed?
