1. Train your neck so it is thicker than your skull, and you're pretty much immune to choke outs. I do isometric holds off the side of a wooden platform using an iron neck harness. I'm up to 5 lbs & 20 minutes prone, supine, left lateral, right lateral. Also makes you resist knockouts and head injuries.
2. Strengthen your tendons and ligaments with weighted isometric holds in various poses and LISS cardio. Stuff like:
> uphill walking on a treadmill for 3 hours once a week
> 3 hours a week of rowing at the highest setting
> extreme range of motion split squats or lunges, perhaps with one or both feet elevated
> forwards and backwards sled pulls
> weighted tib bar holds
> forearm pronation, supination, & extension holds with a band or cable machine
> superman with your arms and legs bearing ankle/wrist weights & hanging off the edge of a box
> as above, but the inverse of a superman - laying on your back, arms and legs dangling and weighted
> isometric cable machine or band holds for hammer curl, triceps extension, shrug, side raise
3. Learn to turn inside the grapple they are trying to put you in (applies to head, torso, hands, feet - always turn inside it), to pull them closer in when they lock around an arm or leg and yank on it, to pick them up and slam them on the ground, and to use your elbows and knees to soften up and distract them.
4. Thicken and toughen your bones by:
> eating beef collagen, vitamin k2, vitamin d3, magnesium
...and harden them in unusual axes by:
> sleeping on a hard bed
> sleeping with a weighted blanket over your body
> putting heavy bags over your head, ribs, pelvis, legs, and arms and constantly moving them against the bag for hours at a time
5. If you're psych-ward maxxing, train bites by biting into a bunch of leather chunks sews together until you can reliably tear chunks out of it, and then go to town on whatever wrestler is fucking with you.
