DO you compete in MMA?
If you are actually serious about it..you won't care about vanity...you'll care more about not getting knocked the fuck out in the fight and making sure your conditioning is good enough to last all the rounds.
Right now I train fighting, but not to the level of where I'm going to compete..in other words I don't do any additional cardio or anything. I go to class 4x a week and train 1x a week at my house on the bag etc. for skills and I just drill drill drill.
That's 5x a week classes..I can handle this + 4 days of intense liftnig caues I've done it so long now.
I can squat 405x10, and the next day have muay thai class and bang out reps of kicks with speed and power (includes push kicks, teeps, knee's, low, mid and high kicks)..and the very next day do deadlifts.
If I'm gonna compete which I will eventually compete again...I will only be lifting 2x a week..full body no nonsense stuff and simnply work on conditioning like a mad man and my skills.
In standup you don't have to be godly strong to be very proficent. Skills is everything.
And for supplements don't even worry about that.
Protein shakes are good for extra protein and recovery. Have one in the morning, one in the afternoon, one after training DEFINATELY.
I recommend fish oil..I take Flameout on this site and I like it.
Creatine is good too.
Take 50mg of zinc a day, and a couple hundred mg of magnesium before bed..multivitamin wouldnt be bad either.
Zinc and Magnesium a bottle of a hundred or more I get under 10 bucks..you can find deals..I usually wait till thers a sale and its 4 bucks off and buy a shitload.
I really don't know how seriosu about your training you are though...
Aside form that if you can't afford any of that shit.
One thing will trump all.
FOOD. REAL ACTAULY WHOLESOME FOOD.
Oh and lots of it.
