Doing MMA without competing? What is that? Hitting bags and sparring? I’m not trying to be sarcastic it’s just that I wonder what that actually looks like? It seems that it’s cyclic in training leading up to the next fight. So, you have however much work that needs to get done in prep and weight to manage for the next rep. Without the competition focus and constant sparring aspect, I’m having a hard time seeing any distinction between that and how I train.
It looks like training any martial art without competing. You hit bags, and spar, yes, but that's not all.
Example if I were to make a curriculum, and assume only one class a day. Places I've trained at normally have multiple classes per day letting people choose what they want to work on, fyi, but for an example this works better.
Mondays/thursdays you do judo, which would consist of warm up, learning what is appropriate for your level for most of the class, then randori for the last 15 minutes (4 3-minute rounds with a minute break in between). During that time you'd be encouraged to use whatever you learned in class.
Tuesdays/Fridays would be muay thai. This is a lot of padwork and sparring. The first 15-20 minutes would be the instructor going over a specific strategy, then if you're a beginner, you'd work with an experienced student or teacher to learn proper form, or if you're more experienced just getting practice and reps in.
Wednesdays/Saturdays are bjj. The instructor shows the move of the day, beginners get separated and drill basics (positional stuff, how to scape mount/sidemount/guard/etc., very basic submissions), while everyone else spends the remainder of the time doing round robin grappling.
Sundays are mixed day. This would be 2 hours. Ideally run by someone who has mma experience, or ranks in the above arts, the first hour would be spent practicing whatever the students who arrived want to work on, and the second would be mma sparring - you start at distance, do striking, and you're free to throw if you wish. After you throw someone, you're free to either back up and let them back up, strike (lightly, this is practice) on the ground while they try to recover, or follow up and get to ground grappling.
Again, the above is assuming one class a day. My experience is you'll have 2-3 classes a day, but also more off days. I can't say if it's different than how you practice, since I don't know how you train. But from my experience with hybrid art, I'd say the biggest difference is in segregating the days rather than trying to fit everything in to one class, and having specific (and different) rules for sparring depending on the class in question.
