One more time, my MMA dudes are angry from lifting weights....-.-

They say there is no need, and I do need some muscle mass, so my question is will body weighted exercises EVER give me some muscle mass, and I do need a complete workout based on body weighted and compound exercises....
I do know push ups/pull ups/crunches...what else...o0

No I mean, I want some muscle mass...looks matter.

You need to get hit in the head a little bit more.

Sorry, what? He does have a life outside of his MMA training incase you didn't realise, he might want to look better for himself and he's fully entitled to do so.  On topic, yes bodyweight will add mass, free weights however will add more mass as a general rule.

Why didn't Mike tyson tire real fast when he knocked out Mohamed Ali LOL! just sayin'

Pwned, from what i understand MMA is mixed combat fighting style so it uses more body parts so more work is need from your heart, where as boxing is more arms so less parts to pump blood to and less work for your heart.

Of course you can gain size for non-MMA purposes, but you should train differently than we who want size do. Bodyweight is the best option here.

I'm guessing the right way to go is that you do exercises like pushups, pullups, burpees, dips, bicycle crunches, inverted rows, walking lunges etc. Instead of doing them 3x10 or whtvr, you do them in supersets or circuits etc. So that you're pushing your endurance in these compounds, doing cardio at the same time, and practicing the mental aspect of keep on going without rest. Yes doing 100 pushups isn't great for mass, but you will gain some mass over time, and your body will probably look really good, albeit not bulging with muscle.

Chest&lat workout:
Pullup-variation (video linked below which shows some interesting variations)
Pushup-variation (clap pushups, hip pushups, one-handed pushup, planche pushups)
Hanging leg-raises
Inverted row (not many variations you can do here I'm afraid)
Decline pushup-variation (staggered decline pushups, increased ROM, one-handed)
Bicycle crunches

Legs&arms workout:
Pistols
Dips / Close grip pushups (easier to get variation on)
Walking lunges (longer steps for glutes)
Chinups
Burpees
Planks

Could be done as a complex, supersets, circuit, etc.

here are some ideas for things you can do

Sometimes weights are needed in MMA training, so I don't see why they are getting angry. Don't let your looks be your primary concern, like the other guys have said, speed and endurance are key to MMA and should be the main focus of your training. However, strength is also important, and that were weights come in. In addition to my conditioning workouts, I do strength training as well. The stronger you are the easier it is to power and oppenent to the mat and lock him in submission and get the tap or simply deliver a knock-out strike. In my opinion, guys that say you only need body weight exercises are only covering part of the picture. Throw in some weight lifting, it does help.
