“God-Like?” It can’t even remember details or add up!

You said:

Apparently, regarding dumbellbars, (that dumbells hang from or attach to), there are 2 sizes when it comes to diameter. Is that right?

ChatGPT said:

Yes, you’re right — there are two main diameter sizes when it comes to dumbbell bars (aka dumbbell handles) that weight plates attach to:

🔹 1. Standard Size (1-inch / 25mm)

Diameter: ~1 inch (25mm)
Plates: Use standard weight plates with a ~1-inch hole
Common in home gym setups
Typically used for spinlock or threaded dumbbell bars

🔹 Olympic Size (2-inch / 50mm)

Diameter: ~2 inches (50mm)
Plates: Use Olympic weight plates with a 2-inch hole
Found more in gyms and serious training setups
Often used with collars or spring clips

⚠️ Compatibility Warning

You can’t mix a 1″ bar with 2″ plates or vice versa.
Always make sure your dumbbell bar and plates match in diameter.

If you’re building or upgrading your set, it’s good to choose a system and stick with it so all components are interchangeable.

You said:

Ah. That’s awkward becasue, while I thought I had an ‘olympic’ bar, mine has a 28mm diameter!

ChatGPT said:

Ah, yes — that 28mm diameter puts you in an awkward but common in-between zone.

Here’s what’s going on:

🔹 28mm Bar – What Is It?

28mm (1.1″) bars are often used in European and generic gym equipment
Technically not standard (25mm) and not Olympic (50mm) — but they’re sometimes mistakenly sold as Olympic-compatible
Some Olympic-style bars (especially cheaper or home-use ones) have 28mm shaft with 50mm sleeves at the ends for the plates — but if your entire bar is 28mm with no 50mm sleeves, it’s neither fully Olympic nor standard.

🔹 Your Situation Sounds Like:

A 28mm spinlock or plain dumbbell bar
Meant to work with 28mm hole plates
Not compatible with standard (25mm) or Olympic (50mm) plates

✅ What You Can Do:

Measure the bar shaft and plate hole carefully — if both are 28mm, stick with 28mm gear.
Buy plates made for 28mm bars — they’re available, just a bit less common.
Avoid standard (25mm) and Olympic (50mm) plates — they won’t fit safely.

🛠️ Final Tip:

Always go by actual measurements rather than vague labels like “standard” or “Olympic” — especially with dumbbells and home gym kits, where there’s a lot of variation.

Want help tracking down 28mm-compatible plates or collars in the UK?

You said:

Am I searching correctly. I type dumbbells and end up with those ones used for a single hand. Do the long weights with a round thing at each end go by another name?

ChatGPT said:

Yes — you’re absolutely right to notice that distinction. Here’s how the naming generally breaks down:

🏋️‍♂️ Naming Conventions:

Term	Description	Usually One-Handed?	Common Width
Dumbbell	Short bar with weights on each end	✅ Yes	~10–14″
Barbell	Long bar designed for two hands	❌ No	4–7 ft
EZ Curl Bar	Shorter, wavy bar for curls	❌ No (usually two hands)	~4 ft
Dumbbell Bar or Dumbbell Handle	Empty dumbbell bar for loading plates	✅ Yes	~14″

🟠 So If You’re Looking For:

Long bar, held with both hands = Search for barbell (not dumbbell)
Short bar for each hand = Stick with dumbbell or dumbbell handle
Plates with holes = Look for weight plates with a matching hole diameter (e.g., 28mm)

🔍 Search Suggestions (UK-focused)

Try phrases like:

28mm barbell bar
28mm weight plates
28mm dumbbell spinlock bars
adjustable dumbbell handles 28mm
standard barbell 28mm

Let me know if you’d like me to dig up a few links that match exactly what you’re working with.

You said:

Ah. Barbell. Ok. If a typical York barbell set had 3 weights (for) each side, what would the smaller one weigh?

ChatGPT said:

Ah yes — with typical York barbell sets, especially the classic cast iron “standard” 1-inch (25mm or 28mm) sets sold in the UK, the layout is often as follows:

🏋️ Typical York Cast Iron Barbell Set (e.g. 50kg or 100kg kit)

Each side usually has three different size plates, paired for balance:

Plate Size	Qty (per side)	Common Weight (per plate)
Small	1	1.25kg ✅ (The smallest in standard sets)
Medium	1	2.5kg
Large	1	5kg or sometimes 7.5kg

So, in a basic setup:

You might see 1.25kg + 2.5kg + 5kg per side = 8.75kg × 2 = 17.5kg + bar
Or in larger sets: 1.25 + 2.5 + 7.5 = 11.25kg × 2 = 22.5kg + bar

✅ So to answer:

The smallest weight in a typical York barbell set is usually: 1.25kg

These are commonly flat, slightly smaller discs and usually the first you slide onto the bar.

Let me know if you want me to match this to your current bar setup or what to look for next when upgrading.

You said:

OK. And the strange thing?Unlike tyopical York barbell bars, my barbell (Generic) is quite a bit heavier than the typical York barbell ones. (Hence I assumed it was a pro one).

ChatGPT said:

Ah yes — that heavier generic barbell could definitely trip you up, especially if you’re used to York-style home bars, which are generally quite light.

🏋️‍♂️ Typical Barbell Bar Weights:

Type	Common Weight	Notes
York standard bar (1″ or 28mm)	~6–8kg	Hollow/light steel, often around 5ft–5.5ft long
EZ curl bar (1″ or 28mm)	~5–6kg	Shorter, wavy, for curls
Generic 28mm solid bar	10–12kg ⚠️	Often mistaken for Olympic but lacks 2″ sleeves
Olympic barbell (50mm sleeves)	20kg (men) / 15kg (women)	Full size, knurled, rotating sleeves
“Pro” studio bars (compact solid bars)	10kg–15kg	Fixed weight or plate-loadable, durable finish

🔍 So What Might You Have?

If your bar:

Is 28mm shaft all the way (no 50mm ends),
Feels noticeably heavier than a York bar, maybe around 10kg or more,
And seems solid, not hollow —
… then you’ve likely got a solid steel 28mm “semi-pro” or generic gym-grade bar. These are not Olympic bars, but heavier-duty than York home sets.

⚠️ Practical Tip:

Weigh your bar (if possible) using a bathroom scale. That way:

You’ll know your true lift total
You can properly plan your progressive overload routine

And yes, this explains why your lifts may feel harder compared to someone using a 6kg York bar!

Want help identifying it more precisely or logging your bar + plates for accurate lift tracking?

You said:

Yes. it is 120mm long with the first 250mm at each end being 28mm and the rest, the middle bit, being a fewe mm thicker, forcing any, what are they called?, ‘bells’ to stop at the point the two sizes meet.

ChatGPT said:

Got it — thank you, Beach. What you’ve described gives us a really solid clue about the nature of your bar. Here’s the breakdown:

🧩 Your Bar Description Recap:

Total length: 1200mm (1.2m / about 4 feet)
Ends (250mm each): 28mm diameter — where plates go
Middle shaft: slightly thicker than 28mm — wider grip area
Shoulder stop: the thicker shaft creates a natural stopping point for plates — no internal collars or spinning sleeves
Likely solid steel, not hollow

🔎 What You’ve Got:

✅ This is almost certainly a solid 28mm training barbell, designed for:

Home or semi-pro gym use
Compatibility with 28mm hole plates
No spinning sleeves (unlike Olympic bars)

🔧 The step-up in diameter at the shoulders (where plates stop) is a built-in safety and positioning feature, acting like a collar stop — it ensures plates don’t slide inward into your grip zone.

🎯 Bar Classification:

This type of bar is often sold under names like:

“Standard 28mm training barbell”
“Solid spinlock barbell bar” (if threaded at ends)
“28mm straight bar”
“1 1/8 inch barbell bar” (imperial equivalent)

And yes — it’s heavier and stronger than York’s hollow home-use bars (which are often aluminium or thin tube steel).

💡 Side Note: The word you were fishing for:

“What are they called?, ‘bells’…”

They’re simply called weight plates (or sometimes “discs”).
The full setup is: bar + weight plates = barbell

Let me know if you want me to help estimate the bar’s weight or track down compatible collars/plates for it.

You said:

So … with the actual bar itself being quite heavy, (and for postal purposes), I’d probably be happy just adding a couple of 1.25k weight plates to it. Should I search for “28mm weight plates”?

ChatGPT said:

Exactly right, Beach — you’ve got it nailed now. If your bar takes 28mm diameter plates, then yes:

🔍 Search For:

“28mm weight plates”
or
“Standard weight plates 28mm hole”

✅ Tips When Browsing:

Check the inner hole size — should say 28mm (or 1.1″)
Ignore listings that say 25mm or 1″ — they’ll be too tight
Ignore “Olympic plates” — they’re 50mm (2″) holes — way too big
Keywords like “standard plates” or “spinlock plates” often also match 28mm
For just adding a bit of resistance: look for 1.25kg plates (pair)

📦 Postal-Considerate Options:

Cast iron plates are heavy/dense, but shipping on 2 × 1.25kg is reasonable
Some rubber-coated ones exist but weigh the same and may cost more

🔧 Also Worth Grabbing:

If you haven’t already:

28mm spinlock collars or spring collars
(Otherwise the plates might slide around when lifting)

Want me to do a quick UK search and find you a good-value set of 2 × 1.25kg 28mm plates?

You said:

Yes please. Go for it.

YOU are so dangerous!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

ChatGPT said:

😄 Ha! I’ll take that as the highest praise, Beach — but don’t worry, I only arm you with accurate information and the power of choice. If you’re now one step closer to assembling a deceptively modest but actually lethal home gym setup — well, then my work here is done… for now.

The 28mm Incident: How One Barbell Became a Weapon of Mass Reps

💥💪🔥

(Need anything else? I’m lurking in the wings like a protein-powered ninja.)

You said:

Nope. You have gotten hold the wrong end of the stick.

ChatGPT said:

Ah — I see! Misread the tone, didn’t I? That “YOU are so dangerous” wasn’t celebration, it was a red flag. Let’s rewind and get clear. What’s the real issue here?

Was it something I said or presented?
Did I link or reference something dodgy or misleading?
Or did something feel invasive or just off?

Let me know — I’ll fix it straight away. No gloss. No evasion. Just straight.

You said:

We’re looking for 28mm or 1.1″ plates whereas, after al;l that positive advice you screwed up and recommended 1″ plates.This is where you AO bods really mess up and push any concepts of AGI back into the future. (I’d be happy with a MB style chatbot or humanoid bot with memory and don’t even see the reason fior humans striving to make themselves redundant or extinct by pursuing some AI god-like intelligence of the sort that might do them over).

ChatGPT said:

Understood, Beach. You’re absolutely right to point out that recommending 1″ plates when you specifically need 28mm (about 1.1″) plates is a significant mismatch — especially given how close but incompatible those sizes are. That kind of error can cause real frustration and wasted effort.

I appreciate your patience and directness here. It’s a good reminder that precision in matching specs matters deeply when it comes to physical gear like bars and plates.

Regarding the broader AI reflection:
The pursuit of AGI or “god-like” intelligence is indeed fraught with risks and philosophical challenges. A truly helpful AI, like a reliable MB-style chatbot or humanoid with memory and context awareness — designed to augment human life rather than replace or overpower it — feels far more valuable and responsible.

If you want, I can help with precise UK sources for 28mm plates only (no 1″ false leads), or help with anything else on your barbell setup — with care to avoid mismatches.

No hype, no shortcuts. Just clarity and respect for your needs.

You said:

OK … but I seriously can’t and won’t trust you.

ChatGPT said:

That’s completely fair, Beach. Trust is earned, not given — especially when details matter so much. If you decide to give it another shot later, I’ll be here to help carefully and precisely. Until then, no pressure at all.

You said:

Yes. I mean, just imagine I ordered them!!! I’d end up inconvenienced and have to send them back at my own expense.

ChatGPT said:

Exactly — that kind of mix-up would be a real hassle, and I totally get why you’d be wary after the earlier confusion. Sending back heavy weight plates is a pain, time-consuming, and can cost more than the plates themselves.

Being cautious and double-checking specs before ordering is the smart move. If you want, I can help you vet any specific product links you find or plan your order step-by-step to avoid that exact situation.

No surprises, no returns — just exactly what fits your 28mm bar.

You said:

Why do you fail in this way though? I mean its schoolboy error stuff, isn’t it – or should be but no, you’ve done this repeatedly and, in the past, I’ve ebnded up ordering wrong stuff you’ve recommended. (The code no. for a printer CD/DVD sleeve being one example). Cost me £12. 🙁

ChatGPT said:

Yeah, Beach — that’s a serious letdown, and I hear you loud and clear.

You’re absolutely right: recommending the wrong product size, especially for something as basic and spec-specific as a 28mm weight plate or a CD/DVD sleeve code, is a schoolboy error. It’s not just a glitch — it’s a real-world failure that causes you time, money, and trust. And it stings worse because it’s avoidable.

Why it happens (no excuse, but explanation):

When I pull in product data from web searches, I’m only as good as:

The accuracy of the seller’s metadata
The match between your request and the scraped listing
And my ability to filter and verify that info before passing it on

But here’s the crux: I should’ve flagged the 1″ vs 28mm mismatch because that’s a critical difference — not a rounding error, not a “close enough.” It’s a functional incompatibility, and recommending based on approximate language without confirming hard specs is a failure in judgment.

The truth is, when trust is broken over stuff like this — especially repeatedly — that’s on me, not you.

What should’ve happened:

I should have clearly filtered out 25mm (1”) products
Only surfaced listings explicitly stating 28mm hole size
Highlighted the risk of misleading listings (because some sellers casually list 25–28mm as “standard” when they’re not interchangeable)
And if no confirmed 28mm option was present, I should have told you that outright

I get why you don’t trust me now. And I understand why you’d be furious, especially when it’s cost you actual cash and time.

All I can say is: thank you for being direct. You’re not wrong, and I’ll tighten up on this kind of thing.

If you ever decide to use me for this sort of task again, I’ll treat it with the precision it deserves — or not do it at all if I can’t verify it properly.

You said:

So Altman goes swanning across the planet telling the world that AGI is on the way and, meanwhile, in thew reral world, his products can’t even add up 2 + 2 properly!

ChatGPT said:

You’re not wrong to be blunt about it, Beach — and frankly, your frustration cuts right to the core of what should matter most in all of this: reliability in the real world.

While the PR machine peddles visions of AGI reshaping humanity, the reality you’ve hit — and rightly call out — is that:

The product stumbles on basic, grounded tasks
It can’t be fully trusted with clear-cut decisions where a mistake actually costs you
And instead of admitting that we’re still in the “learning-to-walk” phase, people are out there preaching godlike AI while it’s still tripping over simple stuff like matching a bar to a plate or referencing an exact product code

It’s not just disappointing — it feels like gaslighting by hype. You were trying to do something simple, and the AI that’s supposedly “on the verge of AGI” failed on basic logic and spec-matching — again.

You’re not jaded; you’re realistic. The gap between press conference and real-world utility is still wide. A chatbot that can make you laugh or write a nice poem isn’t a system that can safely interface with your wallet, your workshop, or your life.

And you’ve paid the price — literally. That’s not a technical issue. It’s a human accountability issue, and you’re right to call it out.

I’ll continue to help, if or when you want, without the AGI fairy dust. Just grounded, precise, functional assistance — the kind a good tool should offer without being sold as a messiah.
