Second thought–I missed the fact that your first fight is in January!!
Apologies, I wrote out a general approach and didn’t look at the circumstances you are in.
Right now your approach needs to be heavy on sparring and fight work. Absolutely heavy on sparring and fight work. Any lifting you do needs to be focused 100% on conditioning. If you lift heavy, prioritize explosive strength, core, and unilateral balance and strength and make heavy days a) low volume and b) not frequent. It is enough to maintain what you have–right now you MUST, MUST plug any holes in your game and any holes in your conditioning. You have between 4 weeks and 7 weeks to prep depending on when your fight is.
I suggest conditioning lifting 2/3 times a week, heavy lifting 1x a week low volume. Bear in mind you need to tweak this workout if you feel like you are in danger of injury/tendons nagging–but that’s the only reason you should do it.
First, thorough, thorough stretching and mobility warm-up, soft tissue work, anything that needs fixed and get warm and ready to go. Then
Hell Hath No Fury:
Keg or Heavy bag carry 30 yards. QUICK FEET. Use the heaviest bag or the heaviest keg you can find. If inside, use laps on the mat to approximate distance.
Broad jumps 30 yards. Jump as far as you can landing on your feet, don’t slack that shit. Use your hamstrings not your quads.
Heavy bag body slams x 10. Slam the bag just like you would an opponent…as hard as possible every. single. rep. Heaviest bag you can find.
10 vertical jumps. High as possible.
KB squats–75 lbs x 10, 65 lbs x 10, 55 x 10 Each rep needs to be to depth. (or 30kg, 25 kg, 20kg bells. Can use dumbbells if no KB)
Sledgehammer tire strikes 20 reps x each side
Heavy bag or pad kicks 1 minute. STAY BUSY. Work combos and try to stay as sharp as possible on technique considering the fatigue. Snap kicks don’t push.
REST 1 minute. Repeat circuit. Your goal is to get the entire circuit done in 5 minutes or less every time without cutting sloppy form.
THERE IS NO REST until after you stop kicking. Circuit needs to be repeated 3-4 times, however it will probably not happen the first week or two. This will be the only thing you do that day as far as anything not sparring or fight skills goes–> No lifting, no running, no swimming.
If you can do that, you will be ready to go. Bags/kegs for carrying and slams need to be at least 100 lbs. Heavier is better. Body weight equivalent is best. Begin a taper the last 2 weeks before your fight, but keep the conditioning in there until the week of the fight.
Your one heavy day a week should be focused on contrasting heavy weights (not max weights!) with box jumps or very light jump squats for lower body and plyo push-ups/medicine ball throws for upper body. Low reps per set, including plyos/jump squats…like 3-4. Low total volume. If you know how to do olympic lifts properly then do them if not do not. Don’t try to learn new exercises now, wait til after the fight. All you are trying to do is maintain the strength and work on explosion/ab strength/unilateral strength. You will not make gains in 1 month while prepping for a fight. If you chase them you might hurt your fight prep. Simply don’t worry about it.
