I concur about the back lacking. I do the following on back day:


military press 5x5
side laterals 3-5x8-10
deads 5x5
chins 2x8-10
shrugs 2x8-10
rows 2x8-10
bent over laterals 2x8-10

Your back is a VERY important and is very major in overall growth/development.

Also, a 5lb tub of protein is only like $25 or so from http://www.bulknutrition.com and 2 scoops x 2 shakes a day that will last you about a month (26 days or so I believe?) and is an extra 80g of protein a day.
