Hi. I know it's been a while since I posted this but I've made some changes including work so I'll mention those for anyone who cares and to the guys who've replied already, thanks for the info and encouragement!
I am now working monday and wednesday's 12pm to 9pm. That is the day the truck arrives with at times 700 boxes or more of clothing and other goods. Fortunately I don't have to lift too many; they go down rollers and we just take whatever is in the box out for the most part. Still it is very physical, including hanging and folding thousands of shirts, pants and other clothing every day, moving constantly. The other weekdays are still 7am to 4pm.
Here are my stats, etc: 6'2" male, 180 lbs, athletic build but not large. I eat very healthy (almost all organic/natural and spread meals out to 6 times per day); I had been keeping track for a few weeks until I started my most recent job. I know it was helping me to control eating urges I often get having had a written schedule (eat every 2-3 hrs) but I can't eat the same quality (or portion) meals or as consistently at work as when I was home not working. I'm sure my metabolism is high. I am able to eat whatever and whenever and don't gain weight very easily, though since I began eating exclusively health food I don't do that nearly as often.
For supplements I take fish oil (3 gel caps/day), multivitamin (iron free, 1/day), and 1 extra calcium cap a day because I don't drink or eat dairy products for the most part, by choice, not intolerance. I also just bought a 5lb tub of ON 100% whey (the natural version of course

).
Ok. My goal is to get bigger, and feel better. And if I have the ability to gain muscle well I may shoot for as big as I can get. This is the first time I have weight-trained. I didn't even do any back in high school gym class. All my muscle is from karate, skateboarding, biking, etc. The routine I have is just a bunch of exercises I put together reading Weight Training for Dummies, and Gold's Gym Encyclopedia. And this past Thursday was my first official weight workout ever.
