jappo, i feel your pain on the cross training bro. What style(s) do you study, and how often are you in the dojo (dojang)? As much as i hate to say it, if you are training excessively that will keep you from putting on muscle mass. Listen to what 0311 has told you, and check out 'clean bulking 101' its a great how to eat clean.

you have a great base, and the metabolism I would kill for. soak in as much as you can here and get growing. And keep the questions coming, we are all here to help
