Add another vote for functional workouts. You don't need to be huge to be strong. Also, what good is there in a great bench-press or curl. They both focus on isolating 1-2 muscle groups and working in a single plane. THAT is not real world. Real world uses multiple muscle groups in multiple planes.
I used to be very thin, too. I made it through Army boot, our academy and even our special operations training when many muscle-heads around me had harder times and/or failed out. So, I never felt insubstantial, but I always wanted to bulk up a little. It wasn't until I let off on my running a bit, that I was able to pick some weight up (I ran track in college and did a lot of recreational running).
I started to focus on lifting and worked on my diet (I ate a ton of calories with a pretty clean diet). I gained some good weight (from 175 up to about 210 or so) and strength. It was when I started cross-fitting that I got some good tone and got even stronger, all while losing a few pounds. It is very intense and has more real-world functionality than most traditional weight-lifting programs.
I've started running a little again (2-3 times a week). These days, I do it more for relaxing and the "me time" out on the trails. I'm still sitting around 200lbs or so, but am content with the fact that I will (hopefully) thin out as I age... and I'm getting about that age to where it starts. LOL
