I need advice on Building muscle

[joetn]

I'm 30 years old
5'9ft 157lbs

I have been bodybuilding ON and OFF for years
My body has been pretty much the same
Goal is to get lean and maybe get to 165lbs eventually

I eat kinda healthy usually goes like
Around 2000calories 130-150g protein, 80-110g fat, 110-150g carbs

Breakfast: Omelette olive oil + peanut butter toast
Lunch: Steak+potatoes/rice
Yogurt/Protein bar + Oats

Training goes like 4sets 10reps
Day 1 Chest/triceps
Day 2 Back/Biceps
Day 3 Legs/shoulders

I'm lifting light these days since I have a bad herniated disc
I also have bad genetics meaning that food goes to my belly only
