I've noticed gains in my arms and legs (str and mass) but my chest hasn't changed at all.
I weight 150lbs
I use creatine mono and take whey. I eat a SHIT load of protein (chicken, tuna, eggs), but also a lot of crap (no desserts/sugar but pizza is my favorite food).
I don't have a routine set in stone but the exercises I do are flat bench, incline bench, skullcrushers, pullups, dips, squats, deadlifts, hammer curls, rows, and shrugs (not all on the same day). I usually do 5x5.
can anyone give me advice? do I need to change my routine for my chest to develop? change my diet? obviously something isn't working
