How Much Does an EZ Curl Bar Weigh?

The EZ curl bar at your gym most likely weighs 18-22 lbs. Round it off to 20 lbs as an estimate.

That isn’t necessarily the case, though. Let’s look at some variants that could weigh different amounts.

If you have a scale available, the easiest way is to simply weigh the bar, either by holding it up carefully on its edge or by weighing yourself with and without the bar in your hands.

With no scale on hand, you can make a pretty good guess.

First, determine whether it’s a standard or olympic bar. They function much the same but have a large difference in weight and look a bit different.

Weight of Olympic EZ Curl Bars

An olympic EZ curl bar has the larger 2″ diameter ends that rotate. A standard bar has 1″ ends that are the same as the 1″ shaft diameter and do not rotate.

The best way to estimate the weight of a curl bar is to look at a few different brands as examples.

Typical 17 lb olympic curl bar

Above is a typical curl bar that is made by many manufacturers, all indistinguishable from each other. This particular one is the Marcy SOC-49 weighing 17 lbs, and it looks much the same as the CAP OB-47 weighing 16 lbs. They might literally be the same exact bar, if you account for the collars that CAP includes that weigh about a pound.

The typical inexpensive olympic curl bar like that is 4ft long and about 20 lbs. There are thousands and thousands of those floating around.

30 lb Rogue curl bar

On the heavy end of the spectrum, Rogue’s 54″ (or 4.5′) curl bar above is 30 lbs, unusually heavy for a curl bar. This speaks to the quality of its construction.

Rogue put knurling over the entire shaft, with the exception of the very middle. This is in contrast to most other manufacturers who cheap out and knurl only some portions of the shaft.

Troy also makes a 5ft long olympic curl bar that weighs 31 lbs. As with Rogue, the shaft between the collars (the part you grip) is the same as a 4ft curl bar, about 32″. The only part longer is the sleeves, to fit more weight plates.

17 lb super curl bar

Above is an example of a super curl bar, with exaggerated bends in it to accommodate tricep exercises too, weighing 17 lbs. This one is made by CAP Barbell, but like the first olympic curl bar I showed further above, lots of manufacturers make one that looks just like this about weighs about the same.

Weight of Standard EZ Curl Bars

A standard EZ curl bar, like all other standard bars, has non-rotating ends that are the same 1″ diameter as the middle shaft portion, made to take standard weight plates with 1.1″ holes.

11 lb standard curl bar

This standard EZ curl bar by CAP weighs 11 lbs. If you look closely you’ll see that the ends are threaded, with spin-lock collars to hold plates on. This makes no difference in the size of plates you’ll use. Whether the ends are threaded or smooth, you use the same standard plates on these.

Yes, I meant York but typed Troy by mistake lol. 100% for sure the grippiness was due to the rust -- it sure wasn't due to the lack of knurling.
