Heavy weights doesn't work that well for ectomorphs (which you are). You're better doing lighter weights and more reps (40 sec sets or more -- you need time under tension).

Then you need a huge shake within 30 minutes of working.
Load it with protein, good fats: almonds butter and fruits (bananas, berries) -- I would also throw some potent enzymes in there. You should have at least 700 calories in the shake.
