Thanks for sharing with us Killian.

Your definately a lean guy, but this can be very beneficial when starting because you won't have as hard a time cutting later on. Get a good bulking diet and you should be able to put on some muscle in no time. If you want some good basic info on bulking look for Dave's post on Clean Bulking as it has a good example diet to follow. Basically, if you can see it, eat it!
