I didnt wanna get into the whole lifting thing, but i wouldnt say bodybuilding. personally i never got into bodybuilding, i got more into the power lifting/strength training thing. Either way im kinda split on things.
If you can get a lot of endurance and dont gas then keep doing what your doing. But if you gassing really hard then you gotta change things up. The thing is my strength is an asset, being strong you can get out of or do things weaker guys cant do. The most common is power bombing the shit out of somebody who tries to triangle choke you.
The flip side is i did find i tired a lot faster in areas i had built up, like my shoulders and arms that was built up more from a BB type routine then from labour jobs growing up. It just gets heavy and acidic really fast.
I think the biggest problem you'll have is time. Unless you got a job that affords you a lot of time to train or basically dont want to do much else with your free time, it's gonna be tough to fit everything in. you want to train in JJ 3 times per week in order to get anywhere. To maintain a proper split would be rough on top of it.
But if you can pull it off, more power to you! Do what works.. everybody is different.
