This. Don't be afraid to eat!! I was probably as skinny as you when i started, roughly 165 pounds. Got up to 212 last January and now cut down to 182 for Mr. Olympia expo, lol...now time to bulk...
You should definitely go if you can find a decent price on flight + hotel. I paid $344 for flight and 4 nights of Hotel, granted I was at 'The Quad' (old Imperial Palace) which isn't the most fancy...
The expo is awesome!! The amount of freebies is insane. I got 101 individual packets of protein alone, haven't counted pre/intra workout samples. The best was a free 30 serving tub of c4. My brother...
