As I said, if you want to increase strength without gaining weight, practise the movements you want to get strong at. Unless you're actually weak, in which case a 12 week block of my workout wouldn't hurt. But if you have a reasonable level of strength, getting better at lifting weights without increasing muscle won't help your strength in MMA, rugby, car pushing etc.ok so this is where I think your program is specific.
you're already strong and in shape. you've exceeded triple bodyweight squat! what about the guys who do want/need to increase strenght while staying within a weight class? (other than playing the sport itself)
and if my questions are FAQ then I'm way more comfortable annoying you...
If you want more strength in MMA, you have two options - get bigger and/or get better at MMA.
