A preacher curl may look like a simple biceps exercise, but there is one detail that can make your workout records inaccurate: the weight of the bar itself. If you only count the plates, you may underestimate the amount of resistance you are actually using. The question “how much does the preacher bar weigh?” does not have one universal answer because curl bars come in several sizes and designs.
Most people performing preacher curls use an EZ curl bar. However, an EZ bar used at one gym may not weigh the same as another. The material, length, sleeve design, and manufacturer can all affect the unloaded weight.
This guide explains the typical weight range, the differences between common curl bars, and simple ways to determine the exact weight of the bar in front of you.
How Much Does the Preacher Bar Weigh?
A typical preacher curl bar falls somewhere in the 10-to-25-pound range before plates are added. That is only a general guideline, however. Certain longer or specially constructed bars can fall outside this range.
The type of bar makes a significant difference. A standard EZ curl bar is often lighter, while an Olympic EZ curl bar generally has a heavier construction and larger sleeves.
As a general reference:
| Type of Curl Bar | Typical Weight |
|---|---|
| Standard EZ curl bar | About 10–15 lbs |
| Olympic EZ curl bar | About 18–25 lbs |
| Specialized or extra-long curl bar | Depends on the model |
| Fixed-weight curl bar | Weight is usually marked on the bar |
These numbers should be treated as estimates rather than fixed industry standards. Different manufacturers produce bars with different specifications, so the only way to know the precise weight is to identify the particular model or weigh it.
For example, an Olympic EZ curl bar from one manufacturer may be listed at 20 pounds, while another brand may produce a similar-looking bar with a different unloaded weight.
What Exactly Is a Preacher Curl Bar?
The phrase “preacher bar” can be slightly misleading because it does not always identify a single standardized barbell.
A preacher curl is normally performed while your upper arms rest against the angled pad of a preacher bench. An EZ curl bar is one of the most common bars used for this movement.
An EZ bar has a curved or angled shaft instead of the completely straight design found on a traditional barbell. The different hand positions can make the grip feel more natural for some people, particularly during biceps exercises.
There are also several versions of curl bars. Some use sleeves intended for standard plates, while others are built for Olympic-sized plates. Their dimensions and construction can therefore vary considerably.
That is why two curl bars sitting next to each other at the gym may look almost identical but still have different weights.
Standard EZ Curl Bar Weight
A standard EZ curl bar is generally designed for standard weight plates with smaller center openings.
These bars are often found in home gyms because they tend to be relatively compact and lighter than many Olympic versions. A common weight range is approximately 10 to 15 pounds.
For someone starting strength training, a lighter curl bar can be useful because it allows you to practice the movement before adding substantial resistance.
Still, you should not assume that every standard EZ bar weighs 10 or 15 pounds. The actual figure depends on the manufacturer and model.
If you are purchasing one, check the listed product specifications instead of relying on a general weight estimate.
Olympic EZ Curl Bar Weight
Olympic EZ curl bars are made for Olympic-style plates, which have larger center holes than standard plates.
These bars are frequently seen in commercial gyms and more substantial home gym setups. They are generally heavier than standard EZ bars, with many models falling around 18 to 25 pounds.
Some Olympic curl bars also have rotating sleeves. This design allows the sleeves and plates to move more freely during certain exercises.
The bar’s length, steel construction, sleeve size, and other design features can all contribute to its final weight.
Before loading the bar, make sure you know whether it is a standard or Olympic model. The two systems use different plate sizes, so they should not be treated as interchangeable.
How Do You Calculate the Weight You Are Lifting?
Once you know the unloaded bar weight, figuring out your total resistance is simple.
You need to count both the bar and the plates.
For example, suppose your EZ curl bar weighs 20 pounds. You put one 10-pound plate on each side.
The calculation would be:
20 + 10 + 10 = 40 pounds
Your total load is therefore 40 pounds, not 20 pounds.
Now imagine that the same two 10-pound plates are placed on a 15-pound curl bar. The total would be 35 pounds.
This is important when keeping a workout journal. If you record only the plate weight, your training numbers will not accurately represent the resistance you used.
How Can You Find Out the Exact Bar Weight?
If your gym does not clearly identify its curl bars, there are a few ways to get a more reliable answer.
Look for a Marking on the Bar
Inspect the ends of the bar and the areas around the sleeves. Some manufacturers put the weight on an end cap or directly on the bar.
If you can find a brand name or model number, search for the manufacturer’s specifications. This is usually more reliable than guessing based on appearance.
Talk to the Gym Staff
The gym may have equipment records that list the specifications of its barbells and curl bars.
This is especially useful when a facility has several different EZ bars. They may look similar but have different lengths and weights.
Weigh the Bar
If there is no label and you cannot identify the model, physically weighing the unloaded bar can give you the most direct answer.
Use a scale that can safely handle the bar and make sure the equipment is stable before taking the measurement. If the bar is too long for an ordinary household scale, ask the gym whether it has an appropriate platform scale.
It is better to measure the bar than to assume its weight based on another curl bar. Similar-looking equipment does not necessarily have identical specifications.
Why Should You Know the Bar’s Weight?
The bar’s weight may seem insignificant compared with the plates, but it becomes important when you want accurate training records.
If you know exactly how much resistance you are using, you can make better comparisons between workouts. For example, moving from 40 pounds to 45 pounds is meaningful only if both numbers were calculated in the same way.
This information can also help beginners choose an appropriate starting load. You may find that the unloaded bar already provides enough resistance when you are learning the exercise.
There is no requirement to add heavy plates immediately. A controlled movement with a manageable load is generally more useful than simply chasing a larger number.
Keeping the bar weight consistent in your calculations also becomes especially helpful if you train at different gyms, where the available curl bars may not have identical specifications.
What Weight Should a Beginner Use for Preacher Curls?
There is no universal starting weight for preacher curls. Your appropriate load depends on your experience, strength, and ability to perform the movement under control.
If you are new to the exercise, try the empty bar first. Perform several slow repetitions and pay attention to how the movement feels.
You should be able to raise and lower the bar without using momentum or shifting your upper arms away from the preacher pad.
If the empty bar feels comfortable and you can maintain good control, you can increase the resistance gradually.
On the other hand, if you have to swing the bar, shorten the movement, or use your body to complete repetitions, that is a sign that the load may be excessive.
More experienced lifters may use substantially heavier weights, but the appropriate number will vary from one person to another.
Is a Preacher Curl Bar the Same as a Regular Barbell?
Not exactly.
A preacher curl bar is commonly an EZ-style bar, which is shorter and has angled sections along the shaft. A traditional Olympic barbell is straight and substantially heavier.
A standard Olympic bar is commonly around 45 pounds, whereas many EZ curl bars weigh considerably less.
The curved design also changes the hand position. Some lifters prefer this grip for biceps exercises because it feels more natural on their wrists, although individual comfort can differ.
For preacher curls, the important considerations are whether the bar fits the bench, works with your plates, and allows you to maintain a stable and comfortable grip.

Frequently Asked Questions
Is a preacher bar usually 20 pounds?
It can be. Some preacher curl bars weigh approximately 20 pounds, but that number should not be considered a standard for every model. Other bars may be considerably lighter or heavier depending on their construction.
What does an EZ curl bar weigh without plates?
An unloaded EZ curl bar can weigh roughly 10 to 25 pounds. Standard versions are often on the lighter side, while Olympic models are commonly heavier.
For the exact figure, check the manufacturer’s specifications or weigh the bar.
Are preacher bars and EZ curl bars the same thing?
Not necessarily. EZ curl bars are frequently used for preacher curls, but “preacher bar” is more of a general description of the bar being used for the exercise than the name of one specific standardized product.
Does the bar count toward the weight I lift?
Yes. If you are recording the total resistance, include the empty bar along with every plate attached to it.
For example, a 20-pound bar with 20 pounds of plates gives you a total load of 40 pounds.
Is a 20-pound curl bar too heavy for a beginner?
That depends on the individual. One beginner may handle a 20-pound bar comfortably, while another may need a lighter bar.
Your starting point should allow you to perform the exercise with controlled movement and appropriate technique.
Can a straight Olympic bar be used for preacher curls?
It may be possible if the bar works properly with your preacher bench and you can grip it comfortably. However, many people choose an EZ curl bar instead because its angled grip provides a different wrist position.
Final Answer: How Much Does the Preacher Bar Weigh?
There is no single weight for every preacher bar. In general, an unloaded preacher curl bar is often somewhere in the 10–25 pound range.
The specific number depends on the bar’s design. Standard EZ curl bars are often around 10–15 pounds, while many Olympic EZ bars fall closer to 18–25 pounds. Specialized models can be different.
If you want an accurate number for your own workouts, identify the bar’s manufacturer and model, look for a weight marking, or measure the unloaded bar directly.
Once you know its weight, remember to include it when adding up your plates. That small step makes your workout records much more accurate and gives you a better way to monitor your strength progress.
