muscle groups
 

What do you feel are your most under developed muscle groups?

My c**k! Lol!!!
No in all seriousness, I think it would have to be my Hams, They are lacking a bit behind everything else, But I have to say in the last couple of months they have really started to catch up.

for me its chest and bi's, when I started to train, I hit the muscles that others didnt like, which I thought were more important then other muscle groups such as quads, hams calves and forearms. I didnt like how some guys looked...like guys lacking calves or forearms..I made fun of them in my head, I was never a jerk to them just was think in my head..lol so I hit those parts first and became addicted to it so I trained them harder then chest and bi's
