Meat, eggs, milk, and spend some days training to just eat more than humanly possible. A whole day where your goal is to eat more than you have ever before. Don't die.
Besides that, get the "7 Sacred Mushrooms" supplement and a men's liquid multivitamin with some men's herbs in it. 1 week on 1 week off.
Go hard on the weights. Focus on grip, neck, jaw/bite and feet/ankles/calves, and on the weak sides as well. You almost want your hands to be as strong in opening or extending them as in closing them, or lifting your foot rather than pushing it down/back, or lifting your head up with 3 pl8s on each side; something like that.
Farmer's carries are great. Get a grip trainer. Use a container (protein, oil, nuts, whatever) that you can fill with water or rocks and lift by the lid; front raises, lateral raises, bent over posterior raises – just bend over a bit then extend your straight arm backwards with the weight in hand to hit the rear shoulder and such; upright raises, just plain holds, get creative but focus on increasing total volume each week and month (weight x reps). Get some rubber bands or something elastic and wrap your fingers then train opening them or spreading them. Do the same with your toes. Doing stuff with sand is helpful, so get some sand to use for grip work. Training the top of the ankles and hip flexors is something you should learn to do, so get a bit creative and start doing it. Leg lifts and sit ups will train the hip flexors. Hooking your feet under some furniture and leaning back until you hit the failure point then hovering just before it is good. Lifting shit with your feet will train it as well (furniture, again). The neck you have curl, extension, twist, lateral curl. Similar to the wrist.
All in all, make sure you repeat the same exercises every week so you don't hit every muscle, but only once a month or something stupid. Be as thorough as possible.
You need to learn how to fight to the death as well, so start shadow fighting against people stronger and faster than you. The shadow/image training should be against people seemingly impossible to beat or much better than they are in real life. Otherwise you'll just tend towards underestimating your opponent.
Gymnastic movement progressions are a great idea.
Do sledgehammer workouts. Don't be a pansy about them either. You could just dig and fill back in a hole as well, shovel workout.
If you don't have access to a gym, you have to replace deadlifts with static deadlifts. Go try to uproot a tree for 10 minutes, progressing up to an hour. The more intense focus and effort you can deliver whilst doing it, the better the results. Standing on a metal bar and going for a deadlift is also acceptable, but not as interesting.
Bottom line is, you need to pick one and focus on it until it's ironed into your bones. Then you can do a second thing. If you do gymnastics, only do gymnastics until you ARE a gymnast. If you do grip/neck/feet/jaw/etc stuff, do it until you ARE the grip/neck/feet/jaw guy. It must become a granular, intracellular part of your make up before you do anything else. Focus, effort, and thoroughness. Do a light workout that you don't change, every morning, ironing it in. Do a workout every couple of days that has more intensity and progression later in the day.
