Detailed sources on modern heavyweights' training or nutritional regimens?

Liston Tyson and Wlad did 20 minutes of neck crunches per day strengthen neck muscles

 

That's fascinating. Thank you for that.

Note on Holyfield's pushing -- he'd tried the exact same thing with Foreman, so it was something he'd worked on before.

 

I would argue (without having read the book in a long time and going from your summation) that sprinting to the finish at a long run is just finishing the run strong (we always preached ‘finish strong’ and would also do ‘10 seconds’ call-outs on people working the bag to pick it up to end the round so they’d be ‘programmed’ to do so to win close rounds).

That’s different than running wind sprints — like 100 to 400 yards time after time going all out.

Nowadays a lot of guys also do interval running (easiest way is go hard from one telephone to the next, then job to the next, then go hard to the next, etc.) and that wasn’t in vogue in the days of Ali or Robinson or Dempsey or Louis … yet, again, they turned out pretty good haha.

 

I would guess guys like Louis and Marciano mostly stuck to what they experienced in the army, which definitely had nutritionists

when people say "modern strength training and nutrition" they mean when it became a commercial industry, which doesn't guarantee improvements

187lbs vs 187lbs Marciano is stronger than Holyfield

something I haven't seen mentioned, chopping trees/wood

 

Eh, I do not know about that.
He is a boxer, & though derided as a "bodybuilder", his goal is not maximum muscle size & strength, & at 6'6" & weighing in at in the 230's in some bouts-& even at his max which I believe was 254 lbs., I would not expect him to do 650 lbs. or so with deadlifts.

Those numbers & above-more especially for reps-are overwhelmingly accessed by more bulky guys, usually PED enhanced.
AJ would be scrawny by competitive lifting or body building standards, at least if not lifetime natural guys.

 

Just my guess for someone of his build who apparently lifts regularly. I think most do a bit more with a hexbar compared to a regular deadlift also.

I'm a 6 foot, 47 year old office worker who would be around 145-150 lbs with Joshua's body fat percentage and I do reps with 180-185 kilos, so I'd expect Joshua to do significantly more than that in the 5-10 reps range. That was my reference, anyhow.

 

This is confusing-since you only specified Kilos, it would make perfect sense that if you were using Kg for your weight, & you are ~ 320-330 lbs at low body fat, you could easily do the near near 400-408 lbs. for reps you suggest.
But you must have meant you would weigh around 145-150 POUNDS, since otherwise you would be carrying roughly as much muscle mass as anyone per inch, ever.

Assuming you must have meant lbs., I would not expect AJ to do that much more than you.
First you implied you are somewhat heavier than what weight you would be at his BF%, & even that adds something to your lifts.

Mainly though, while AJ is likely way more athletic than you & I & we are not elite boxers, you seem really good at this for your size.
AJ likely can do more, but not necessarily much more, since you may pursue lifting more assiduously for years, are good at it...
And there are always diminishing returns when you get larger bodies.

There are various formulas to consider who is

stronger at various weights, such as the Wilks Coefficient.
Suffice to say it is basic physics that even at the same BF level, smaller bodies can do a higher weight relative to their size, all other things being equal.

Ah, sorry. I meant 145-150 lbs for my body weight, or what it would be with AJ's body fat percentage (sadly it's more like 175 as it is) and since I'm 6'0 I have naturally rangy build, even though my belly doesn't really agree nowadays.

I've done deadlifts on and off for the last 10 years or so, gone years without doing them during this time, and with a hex bar for the last 16-17 months. So I haven't really been focusing that much on it, only in periods, and from that point it seems reasonable to me that Joshua would do pretty much more.

 

Ah well you likely have near maximized what you can do.
Unless you do or add PEDs-although if you have, that can extend your potential even when you are clean due to cellular changes. Although I am strongly against all of them, even creatine.
My best for a single rep was 440, & although with a suit &/or wraps I could have done more, but not dramatically so. Thus your rep ability means you are better than I ever was at it.

Muscle has memory so it is not so hard to get back to where you were after lay offs.
Then you have done them for some extended periods, like nearly the last year & a half.

AJ is gonna be doing much more than you for overall physical ability unless you are a fitness fanatic.
But that does not mean that he is trying to maximize DL strength-you may have done as much or more for that simple goal.

You did not address that there are diminishing returns for extra size, even if it is pure muscle, so given all of this it is reasonable that Joshua can DL more than you, but not necessarily dramatically more.

Where do you see that Sharkey's legs are even as big as Hackenschmidt's, or nearly as strong, as a legendary strongman or wrestler, let alone way bigger than his? What image of Sharkey's legs looks like this: [url]https://www.alamy.com/george-hackenschmidt-1877-1968-early-20th-century-baltic-german-strongman-and-professional-wrestler-who-is-recognized-as-professional-wrestlings-first-world-heavyweight-champion-image235041166.html[/url]

 

About the Marciano routines. Is what Rock did really that unrealistic compared to say David Goggins? Just a random thought.

 

Thanks yes he had a lot of overall mass!
Looking at many photos their legs were comparable.
Did you see my question about whether when you wrote "no faster" or "no more than" a certain speed or weight, if that means it was likely close to that level, or you have no idea?
