Body getting cut but too skinny and need to get bigger. How and best way ?

[GutShot]

short tight muscles?

exercising does not shorten the bones, thats the only way to physically shorten a muscle, reduce the length it has to span.
Lean means to have little fat on, they guy has no problems in this area

I am 190lbs and people from my Taekwondo club will hardly describe me as slow

I haven't changed the guys training routine as he is geared to boxing but weights are an essential tool in all sport training.

Ok thanks all for the info...Will try this diet and do more of what I am doing already....will have to work up to a 1000 crunches that sounds kinda crazy but I guess not, as far as the pullups will really have to work on those I can only do about 10.
