A good wrestling background always helps MMA, but I would personally lift and do MMA. There are some good lifting/cardio workouts on bodybuilding.com, it doesn't cost anything, you just have to sign up. I recommend the workout Shortcut to Shred. It works cardio and muscle. You'll be exhausted at first, but it will get better.

The problem is not that you are small, your problem is that you think that your size disadvantage will lead you to failure. Training with bigger people is better than training with people your size. Why? Because when you do a MMA fight, you will be the more technical fighter out there. How? Because you trained with bigger guys, and you had to develop smart ways to defeat them.

Lift and do MMA, the more strength, the better.

squat, deadlift, MMA. do these 3

I started training in MMA when i was 19 years old. I did wrestling when i was 17-18 years old. Now im 20 and my problem is that i keep training in a inconsistent way. Last summer i was at the gym 4pm and i was out around 10pm Mon-Fri. MMA was my life and i always wanted to keep and reach to the top level. Every since the beginning of this year, ive been slacking. I be going to the gym for a week then ill stop for 3-4 months straight. Mainly my problem is that im small. I'm only 5'7 weighing 135 with a slim body frame. Jiu Jitsu is my problem and everybody at my gym probably outweighs me by 40-200 pounds. I feel like im not getting better, my mind is draining, i feel like giving up which i did already. Im at a point where i was thinking i should lift to bulk up, and do wrestling in college for 2 years. After graduating from college, then i will probably head back to MMA training. Is this a smart idea? Should i just stick to MMA (Muay Thai and BJJ) and progress from there even though im small? Should i just bulk up and do wrestling for 2 years THEN do MMA? I feel like my mind is bipolar because one day i want to train but the next day i want to lift and i cant make up my mind. Or should i just say forget MMA and lift?
