What is an EZ curl bar?

An EZ curl bar is a short barbell with a zig-zag or 'W' bend in the middle that creates angled grip positions. Those angles let you hold the bar with your palms semi-supinated (halfway between facing up and facing each other) instead of fully turned up, which takes strain off the wrists and elbows during curls and triceps extensions. It's a supplementary bar, used mainly for arm work.

How much does an EZ curl bar weigh?

It varies by model, but most EZ curl bars weigh roughly 10 to 25 lb (about 4.5 to 11 kg) depending on length, sleeve type and whether it's a lighter standard bar or a heavier Olympic one. Unlike a 20 kg Olympic barbell, EZ bars aren't standardized to one weight, so check the specific bar's listed weight and factor it into your loads.

Why use an EZ bar instead of a straight bar for curls?

The angled grips let your wrists sit in a more natural, semi-supinated position rather than the fully supinated position a straight bar forces. For many lifters that's noticeably more comfortable and lets them curl and do triceps work — like skull crushers — without the wrist and elbow strain a straight bar can cause. A straight bar hits the biceps a bit more directly; the EZ bar trades a little of that for joint comfort.

Does an EZ curl bar fit Olympic plates?

Only if it's an Olympic EZ bar with 2-inch sleeves — those take the same plates as your Olympic barbell. Many cheaper EZ bars are 'standard' bars with 1-inch sleeves and need 1-inch plates, which won't fit an Olympic bar. If you want to share plates with your main bar, buy an Olympic (2-inch) EZ bar and check the sleeve spec before ordering.

The EZ Curl Bar, Explained

The EZ curl bar is the short, zig-zag bar you’ve seen in every gym — and its bent shape is doing a real job, not a decorative one.The “W” bend creates angled grip positions that let you hold the bar with your palms turned partway up rather than fully up. That small change takes meaningful strain off your wrists and elbowsduring curls and triceps work, which is why so many lifters reach for it over a straight bar for arm training. Here’s the full picture.

What the angles actually do

Hold a straight bar for a barbell curl and your forearms are locked in full supination— palms turned all the way up. For some people that’s fine; for many, it strains the wrists and the inside of the elbow, especially under heavier loads or higher volume. The EZ bar’s angled grips let you sit in a semi-supinated position (palms halfway between up and facing each other), which most lifters find far more comfortable on those joints. The trade-off is small: a straight bar hits the biceps a touch more directly, while the EZ bar sacrifices a sliver of that for joint comfort and lets you keep training arms when a straight bar would nag.

What you use it for

The EZ bar is an arm-work specialist. Its bread and butter:

Barbell curls — the angled grip is the whole reason the bar exists.
Triceps extensions / skull crushers — the semi-supinated grip is much kinder to the wrists here than a straight bar.
Close-grip and reverse-grip variations — the multiple angles give you grip options a straight bar doesn’t.

It is nota replacement for your main barbell — you won’t squat, press or deadlift with it. It supplements the big bars once your Olympic bar, rack and plates are sorted.

Sizing: Olympic vs standard

This is the spec that trips people up. EZ curl bars come in two sleeve sizes, exactly like full-size bars:

Olympic EZ bar (2-inch sleeves):takes the same plates as your Olympic barbell. Buy this if you want to share plates with your main bar — it’s the convenient choice for a home gym that’s already Olympic.
Standard EZ bar (1-inch sleeves):cheaper and lighter, but needs 1-inch plates that won’t fit an Olympic bar. Only sensible if you already own standard plates.

Check the sleeve size before you buy, and remember to lock your plates — a short bar tips easily if a plate creeps, so a pair of collars is worth it here too.

What it weighs

Unlike a standardized 20 kg Olympic bar, EZ bars aren’t a fixed weight. Most land somewhere around 10–25 lb (roughly 4.5–11 kg)depending on length and sleeve type — a heavier Olympic EZ bar toward the top, a light standard bar at the bottom. Because it varies, check the specific bar’s listed weight and factor it into your working loads, especially if you’re tracking curl numbers.

Is it worth it?

For most home gyms that already have the essentials, an EZ curl bar is a cheap, high-comfort add. If barbell curls or skull crushers bother your wrists or elbows — or you just want more arm-training options — it earns its small footprint and modest price. If your elbows and wrists are happy on a straight bar and you don’t prioritise direct arm work, you can skip it without missing much. It’s a rounding-out purchase, not a cornerstone one — buy it after the bar, rack, plates and bench are covered.
