That is why I have mentioned bodybuilding program - I guess I know the difference... As for weight gain all things being equal, back squat is the numero uno for gaining mass, fighters have problems with recovery, and - as much as I love squats (especially Zerchers), for fighters, big pull is always the drill to go - be it deadlift or eg. powerclean.
The rest - see above AND below:
Strength Training for the Martial Arts
http://practicalhungkyun.com/2013/05...-martial-arts/
Misinformed? Well, apart from martial arts, I am a kettlebell, barbell and bodyweight instructor under StrongFirst (education and strict requirements met, not purchase of a certificate). I actually taught with Pavel Tsatsouline last year in Sweeden (and with Swedish Olympic wrestling strength and conditioning coach, and with UFCs Gustaffsons strength coach), and will teach this year in Italy again

I am also a chief-instructor of major Czech strength and conditioning organization called KB5

My wife is strength and conditioning professional (not fitness, strength and conditioning, ok?), with 200 members in her gym (ladies only) - see here

Just recently I have been asked to take under my wing strength and conditioning for MMA certifications/trainers licenses in our country... So yes, I sincerely hope that what I say is not typical, both in TCMA and fitness community :-) and I can definitely say that I know/can lift a bit :-)
