I have been working out spuraticly for the past year and only recently have i had the time to dedicate myself to a more intense routine.
5'10"
180lbs - goal is 200lbs
You seem to have developed a pretty good foundation to work with over the past year. Your also relatively lean will come in handy so you don't have to do a ton of cutting later on once your at your goal.
Hit the weights and the dinner table hard and you should hit 200.
