EZ Bar Weight – Comparing Different Curl Bars

For those aiming to bulk up their arms, the EZ curl bar is a gym staple.

With a myriad of brands and models, pinpointing their weight can be tricky, complicating progress tracking.

Generally, these bars weigh between 2-35 lbs (2.26-15.87kg), when all types of curl bars are accounted for.

This guide will demystify the weights of prevalent EZ curl bars, ensuring you’re never left guessing at the gym.

Let’s get started!

Key Takeaways

Feature	Combined Range	Average (Approx.)
Weight of Curl Bars	2-35 lbs	~18 lbs
Length of Curl Bars	24-74 inches	~48 inches
Diameter of Curl Bars	25-32 mm	~28 mm

Different EZ Curl Bar Weights

There are multiple different curl bars out there, and with them come different weights, lengths, and even overall construction.

I’ll cover the most popular curl bars, including their weight and the main differences between them. 

Standard Curl Bar Weight

A standard curl bar has a 1-inch diameter across the shaft and sleeves, and unlike Olympic bars, the sleeves do not rotate.

They can also have either smooth or threaded collars that use a standard spring or spinlock collars.

Instead of just throwing out a random number on how much they might weigh, let’s use cold hard data to dispel incorrect information.

Here are the most popular standard curl bars including their type, weight, and length.

Brand	Collar Type	Length	Weight
CAP Barbell Curl Bar	Smooth	60”	14lbs
Marcy Combo Curl Bar	Threaded	47”	12lbs
Weider Curl Bar	Smooth	47”	12.5lbs
Marcy TCB-48R Curl Bar	Threaded	47”	11lbs
Sunny Health & Fitness Curl Bar	Threaded	47.2”	11lbs
CAP Barbell RB-48T2B Curl Bar	Threaded	48”	11.55lbs
Champion Barbell Curl Bar	Threaded	48.82”	10.7lbs
HIRALIY Curl Bar	Threaded	47”	10.5lbs
Fitness Gear Curl Bar	Threaded	47”	10.4lbs

Delving into the specs of top-rated standard barbells reveals a few insights.

• Threaded sleeves emerge as the favored collar type, despite their time-consuming nature for loading weights — a clear case of popularity trumping convenience.
• Standard curl bars typically don’t stretch into rackable territory, with most measuring around 47 inches, though you’ll find the occasional 48 to 60-inch exception.
• As for weight, it’s a narrow field, ranging from 10.4 to 14 pounds, averaging out to roughly 11.6 pounds.

In a pinch, you can bank on a standard curl bar weighing in at about 10 pounds for simplicity’s sake.

Olympic Curl Bar Weight

This will be the most common type of EZ curl bar you’ll see in a commercial gym, as they’re safer and can hold more weight than standard bars.

The main reason they weigh more is because of their 2” sleeves that are designed for use with Olympic weight plates.

Plus, the higher weight capacity from a thicker shaft definitely increases the overall weight as well.

Here are the most popular Olympic curl bars, including their important specs.

Brand	Diameter	Length	Weight
Rep Fitness	30mm	55”	30lbs
Rogue Fitness	28.5mm	54.5”	30lbs
Vulcan Strength	28.5mm	47”	25lbs
Bells Of Steel	28mm	47.2”	22.5lbs
Everyday Essentials	28mm	47.24”	20lbs
Synergee	28mm	47.3”	19lbs
Marcy	28mm	47”	17lbs
Rage Fitness	25mm	47”	17.85lbs
CAP Barbell	25.4mm	47”	15.5lbs
Titan Fitness	28mm	47.125”	14lbs

There’s a much bigger selection of Olympic curl bars out there, and their overall weight and dimensions are all pretty similar for the most part.

The vast majority of Olympic curl bars have a 28mm shaft diameter. Some are thinner at 25mm and others are thicker at 30mm.

Most have a 47” length similar to standard curl bars, but some go up to around 55”.

Finally, the weight of an Olympic curl bar will be higher than all standard curl bars. They can be as light as 14 lbs, with the heaviest up to 30 lbs overall.

Overall, you can expect your Olympic curl bar to weigh between 14-30lbs.

Rackable Curl Bar Weight

Rackable curl bars are almost identical to Olympic EZ Curl bars.

The only major difference is that they’re longer, so you can rack them in your power rack, just like a typical Olympic barbell.

These can definitely come in handy if you have the space, especially for movements like skull crushers where you’re lying on a bench.

Because they’re longer than a typical EZ curl bar, it makes sense that they’re going to weigh more overall.

Let’s see if that actually holds true with the most popular options now.

Brand	Diameter	Length	Weight
Rep Fitness	30mm	74”	35lbs
Get RX’d	30mm	74”	35lbs
Giant Lifting	28mm	74.75”	35lbs
Rogue Fitness	28.5mm	74.74”	35lbs
Bells Of Steel	28mm	74.6”	33.5lbs
Titan Fitness	28mm	71”	31lbs

The main feature of a rackable curl bar that sets it apart, is the longer shaft and sleeves.

They typically match the 28mm diameter of Olympic barbells, with a few at 30mm for added durability.

But, as I mentioned, they’re designed longer at around 74 inches to accommodate more weight.

Most rackable curl bars weigh in at 35 lbs, with a general range of 31-35 lbs.

Super Curl Bar Weight

Super curl bars have an even greater bent camber in the shaft.

This type of curl bar is great for taking even more torque off of your wrists and can even be used for hammer curls.

Here are the most popular super curl bars, so we can figure out how much they weigh on average.

Brand	Diameter	Length	Weight
Everyday Essentials	25mm	48”	25lbs
Verve Fitness	28mm	47.6”	22lbs
Synergee	28mm	47.2”	20lbs
Philosophy Gym	25 & 28mm	47”	19.6 & 20.9lbs
XMark	25mm	49.25”	18lbs
Cap Barbell	25mm	48”	17lbs
Sunny Health & Wellness	25mm	48”	16lbs

Super curl bars typically feature a shaft diameter of 25-28mm, akin to standard Olympic curl bars.

Their lengths are quite comparable too, mostly spanning 47-49.25 inches.

Weighing between 16-25 lbs, super curl bars lack a standard weight, presenting a variety in each model that could make pinpointing the exact weight of the bar you’re using a bit more challenging.

Fixed EZ Curl Bar Weight

You may come across different weight options when using an EZ curl bar. Some bars come with a fixed weight, meaning the weight is built into the bar and cannot be adjusted.

This can be a great option for those who want to simplify their workouts and don’t need the flexibility of adjustable weights.

Fixed EZ curl bars typically come in a range of weights, from as light as 10 pounds to as heavy as 110 pounds or more.

This means you can choose the weight that works best for your current fitness level and goals.

Here’s an idea of what fixed curl bars overall dimensions are.

Brand	Diameter	Length	Weight
Titan Fitness	32mm	38.25-45.5″	20-110lbs
Synergee	31.75mm	40.8-48.8″	10-110lbs
Body Solid	32mm	N/A	20-110lbs

Overall, they tend always have a thicker diameter of around 32mm, are between 38-49″, and are available from 10-110 lbs on average.

Tricep/Hammer Curl Bar Weight

A tricep/hammer curl bar is designed specifically for, you guessed it, tricep extensions and hammer curls.

It doesn’t have that same bend in the shaft that EZ Curl bars do, but it does have a pretty unique shape.

The neutral grip position still puts less stress on your wrists and forearms, so it technically counts, I would say.

Here are some of the more popular tricep and hammer curl bars available.

Brand	Diameter	Length	Weight
Bells Of Steel	28mm	34”	25lbs
Synergee	28mm	34”	25lbs
Titan Fitness	25mm	34”	22lbs
Body-Solid	N/A	34”	22lbs
Fitness Maniac	N/A	36”	16lbs

Tricep/Hammer curl bars, while similar to other curl bars in design, boast a more robust build due to their rectangular shape that incorporates more steel.

Typically, these bars come with shaft diameters of 25mm or 28mm. Lengths are predominantly around 34 inches, though some may extend to 36 inches.

In terms of weight, they align with the 16-25 lbs range seen in other EZ Curl bars, with most tipping the scales at 22 or 25 lbs.

EZ Curl Bar Attachment Weight

The final type of EZ curl bar is an attachment used with cable machines.

These tend to have the same cambered shaft to keep your wrists happy, and they revolve as you perform curls, extensions, etc.

Naturally, these aren’t full-sized curl bars, so naturally, they’re going to be shorter and weigh a lot less.

Brand	Diameter	Length	Weight
York Barbell	N/A	29”	10lbs
Iron Company	N/A	28”	8lbs
Rep Fitness	25mm	28.3”	7lbs
Power Systems	25mm	28”	7.8lbs
Cap Barbell	28mm	29.53”	7.5lbs
Inspire Fitness	N/A	24”	2lbs
Body-Solid	N/A	30.5”	2lbs

Handle diameters on curl bar attachments are typically within the standard 25-28mm range.

These attachments are quite compact, with lengths starting at about 24 inches, though most fall between 28-30 inches.

Given their purpose, they’re designed to be lightweight, with the lightest around 2 lbs and the majority ranging from 7-10 lbs.

What Is An EZ Curl Bar?

An EZ curl bar is a versatile piece of equipment designed specifically for exercises such as curls, extensions, upright rows, and more. 

Its unique camber design reduces strain on the wrists and forearms by allowing for an ergonomically friendly grip. 

Curl bars are constructed with steel and coated in materials such as hard chrome, e-coat, or cerakote.

They’re also available in various weights, sizes, and types.

Such as:

• Standard
• Olympic
• Super
• And more!

Whether your goal is to build muscle or get stronger, an EZ curl bar is a great choice for your training.
