Quick question bros. Does olympic barbell allow you to lift more...

you guys should consider just getting stronger rather than padding your numbers

it might depending on how shit yours is
if you can load enough plates on it to make it heavy enough for your compounds, it’s fine but probably not ideal. knurling and bar thickness are important for grip, bar length is important if it’s not wide enough to do an exercise properly (ie you’re gripping at the collars or if you pull sumo, there’s not enough space to get your legs wide enough). Whip (how bendy it is) only really matters for deadlifting heavy weights, and spin (how quickly and smoothly the ends can rotate) only really matters for oly lifting or squatting extremely heavy.

Yes they can hold a lot more weight. It will feel pretty similar lifting the same weight on an Olympic bar as it will on yours, but if an Olympic bar is longer than your current one, you will have to account more for center of gravity/balance of the bar.

good replies. thanks

>you don't count the bar
so 4pl8s is only 360lbs?
You do realize it's easier to bench '360lbs' of pl8s on a 25lb barbell then it is to bench '360lbs' of pl8s on a 20kg olympic barbell, right?

>so 4pl8s is only 360lbs?
correct

So why is it easier when you use a lighter barbell?

lmao dude just get a real barbell. I have never seen a gym with those 25lb bbarbells you are talking about what the fuck

and its easier to bench them without a barbell

You never seen an axle bar?
Sure you can get them in 20kg, but the ones at my gym are between 25lbs and 33lbs.
I don't know what they are, so pic related is either 415lbs or 423lbs.
If I wanted to meme you, I could pretend that it's a 20kg bar and claim 435lbs but I won't, it's too fiendish.

That's why dumbbells exist, user.

> why do Americans care how much they actually lift so they can accurately track their progress

well if you’re looking at it from a structural point of view the bar will yield (aka permanently bend) when subjected to a bending stress equal to its section modulus multiplied by it’s yield stress. section modulus for a solid cylinder is pi*r^3 / 4 = 2144mm3 for a 28mm diameter barbell (standard size). yield stress is hard to know because it depends on material and quality but 200MPa is a good lower point for cast iron or mild steel, so with that we get a yield moment of 428.8 Nm. A standard barbell is 1310mm long between the collars, so let’s take the worst case and say that the longest moment arm is half that or 605mm (this would represent a one hand deadlift, not that you’ll ever do one but it’s the most stressful case for the bar). So to achieve yield on our bar the load on one end would need to be 428.8 / 0.605 = 708.8 N, or 72.3kg under normal gravity. Now if the bar is poorly made there is a chance of failure occurring before then (most common would be shear failure I believe, snapping suddenly at a point where the metal isn’t a nice homogenous solid) but there’s no real way of knowing that without actually testing and failing the bar itself. There’s also the chance of the collars being attached badly and failure occurring there. If the bar is thinner than 28mm it’s failure load will be smaller cubically (half the size would mean 1/8th as strong), and if the bar is shorter the failure load will be a little higher because of the shorter moment arm.
tl;dr you’re unlikely to bend even your shitty bar until you’re diddlying about 160kg
