Did any other fighters use a 300lbs punching bag?

The back allows for more lockout contraction and wrist strength development by making the puncher force the bag to move all of its weight, compared to say an 80lbs punching bag. Only someone with elite hand and wrist conditioning could use such a contraption without hurting themselves. Its similar to breaking a brick in martial arts, if you do not move it/break it, it will break you.

I've seen multiple modern gyms use one, though im sure its only few can use. It's made for athletic outliers (to be used PROPERLY). Ironically enough it'd ruin any puncher had they not been conditioned for it, too many risks of hand injury, they'd either hurt themselves or subconsciously hold back.

 

Interesting. Where did you hear all of this?

 

I came to the conclusion myself. I'm going to college for a strength and conditioning degree after all, I enjoy thinking about these things. Perhaps an official study should be done, but do we really need a study that shows that moving a 300lbs heavybag vs a 150lbs heavybag makes you stronger in the areas a heavy bag is used to develop? In the same light that a 225lbs bench press 1rm would mean that your chest is weaker than someone with a 315lbs bench press 1rm

 

Wow, next they’re going to say that blueberries are useless.
This is getting ridiculous.

I see.

I disagree with your reasoning. I don't see any reason to think that hitting a heavier bag is to more power what benching more weight is to being able to bench more weight. They don't seem that similar to me. A better analogy would be throwing punches while wearing heavy resistance bands or something, and I’m not even sure about that one.

 

I’m my experience a bigger, heavier bag allows you to practice power punching on an object that moves and swings around less.

Which might be what certain fighters are looking for.

You can punch in combos putting full power in each punch, rather than a smaller bag, where if you put full power into the first punch it will move the bag which can ruin the follow up you’re looking for. So I think it can help with a certain kind of form.

If you think about it, live opponents don’t swing around like a heavy bag. People have more resistance than a bag in terms of having their entire body moved from a punch, right?

And yes, I think it can develop power for certain styles. It’ll take some extra strength and power to keep hitting the thing effectively for a normal duration if you’re trying to punch through it.

Just my 2 cents

 

Why would that take extra power?

 

You can usually tell when you punched through a bag with power by hearing/feeling a loud snap. If the mechanic of the punch is good, you usually don’t even feel much resistance in your hand at all. It sort of fits like a glove.

Getting that same result on a heavier bag seems to require a more powerful punch.

 

I couldn't possibly comment.

 

Why though? Your concluding sentence doesn't follow from the previous sentences.

I've hit very heavy bags before and I found that the same punches actually sounded a lot more impressive on them (if they're dense enough). And punching those bags feels better sometimes too, because you can feel the full impact of all your punches going into them. I used to enjoy hitting those bags but I'm not convinced that they improved my power any more than regular 100-150lb pound bags.

 

There is video of Jack Dempsey using a 300lb heavybag on July 4th 1919.

 

Looking at it again, it appears that it does.

 

Foreman.

I hit a 300 pound heavy bag twice.

First time was at the Playboy club resort in Northern NJ back in 73-74. I was a 150 pound athletic 15 year old. I watched Foreman train at the hotel in the afternoon and then went back that evening to find a deserted gym. I gave the bag a couple of whacks and it was like hitting a concrete wall. Next morning it felt as if my shoulders were dislocated.

Years later I went to pick up my daughter at the gym she was working out at. Then I was around 55, 220 pounds. There was a huge heavy bag which I was told was 300 pounds. Again I gave it 3-4 whacks and again it was like hitting an immovable object. Next morning again it felt as if my shoulders were dislocated! Bottom line hitting a heavy bag like Foreman did with abandon takes huge amounts of strength and power. Don’t underestimate the difficulty.

 

Study up gentleman!!
