Starting Strength would be a place to start for training. Your supps will be your diet for now (all you need really, even older guys like Howwedo and me only really need diet to change body composition...and proper training).
For a Lean Bulk:
-1g to 1.25g of protein per pound of BW
-.45g to .5g of fat per pound of BW
-Carbs constitue the rest of you kCals of the day, you find this number like this:
Get your BMR, calculate Total Day Energy Expenditure (TDEE) , that gives you a number in kCals , well now you add some 250kCals to it (and keep adding so every week) the number you get, lets say its 3000 kCals total, you do this:
TDEE-(Protein kCals)-(Fat kCals)=(Carbs kCals)
1g of protein = 4 kCals
1g of fat = 9 kCals
1g of carbs = 4 kCals
So for you at 155 lbs , assuming you start at 3000 kCals:
160g protein
75g fat
420~ grams of carbs.
Around so to get the 3000 kCals , have some wiggle room if you please...anyhow, when you keep adding to the kCals every week or two, add them in the form of CARB kCals , meaning you add most of those 250 kCals from carbs , and some trace protein and fat.
Hope it helps...Oh yeah Google Starting Strength for a beginners training program so you learn how to train properly, if you have some notion of it, as presented...5x5 would be idea.
