You shouldn't belittle yourself like that bro...just by posting up you have more balls than most people. Your BF ?? Hard to tell...but when I'm 10% I know I have major definition in all muscle areas. But you and I are completely different physiques. EAT LIKE A MOTHERFUKKER !! Hammer the protein...but be weary of the carb belly...no one wants that.
My mode of thought:
1. The more you eat the more you will weigh.
2. The more you weigh the more you will push.
3. The more you push the bigger you'll get.
4. The bigger you get the more you'll eat.
5. Return to #1.
Pretty fucking easy bro !! Stick to the basics...push/pull.
Chest: Bench press...incline bench press
Shoulders: Shoulder press (barbell)
Back: Chins...pulldowns...seated rows (wide and narrow)
Biceps: Straight bar curls
Triceps: Skulls and pushdowns
Legs: Depth before dishonor...squat your guts out and GO DEEP !!!
