How Much Does a Weightlifting Bar Weigh, and Should You Count It?
Quick Answer
Yes, count the bar. An IWF men’s Olympic bar is 20 kg (about 44.1 lb), while some US power bars are manufactured at 45 lb. A 45 lb bar plus one 45 lb plate per side totals 135 lb; a 20 kg bar plus one 20 kg plate per side totals 60 kg. Those are different loading examples, not exact conversions.
Common Questions—Answered Fast
“How heavy is the bar?”
“How much does a bar weigh on bench press?”
“How much does the weight bar weigh?”
These questions concern the unloaded bar or, on a Smith machine, its effective starting resistance. Check the end cap, equipment label, or manufacturer before logging; appearance alone cannot establish the weight.
Types of Barbells & Their Weights
Olympic / power bar — IWF men’s bars are 20 kg (44.1 lb); some power bars are labeled 45 lb (20.4 kg). Use the actual specification.
IWF women’s Olympic bar — 15 kg (about 33.1 lb), with a 25 mm shaft that may suit smaller hands. The competition name does not restrict who can train with it.
Technique bar — deliberately lighter, with model-specific weight and loading limits. Check its label.
EZ / curl bar — model-specific. For example, the Rogue Curl Bar is 30 lb (13.6 kg); many shorter bars are lighter.
Trap (hex) bar — model-specific; handle design, frame, and open versus closed construction affect the unloaded weight.
Smith-machine bar — use the machine’s stated starting resistance, not a universal bar mass. Counterbalance and rail design vary.
Safety-squat or cambered bar — model-specific; padding and frame design can substantially change the weight.
Axle (thick) bar — model-specific. The Rogue Axle is 25 lb (11.3 kg), showing why a thick shaft does not imply a 44–55 lb bar.
Bar Type | Unloaded weight / starting resistance | Best Use |
|---|---|---|
Standard Olympic / Power | 20 kg (44.1 lb), or labeled 45 lb (20.4 kg) model | Squat, bench, deadlift |
Women’s Olympic | 15 kg (33.1 lb) | Olympic lifts, smaller hands |
Technique | Check model; lighter training bars vary | Learning form, youth athletes |
EZ / Curl | Check model; Rogue example: 30 lb (13.6 kg) | Biceps curls, triceps extensions |
Trap (Hex) | Check model; no universal weight | Deadlifts, shrugs |
Smith‑machine* | Read machine starting-resistance label | Guided bench/squat variations |
Safety‑squat / Cambered | Check model; no universal weight | Squat variations |
Axle (Thick) | Check model; Rogue example: 25 lb (11.3 kg) | Grip‑intensive lifts |

Should You Count the Bar on Bench Press, Squats, and Deadlifts?
Yes. Include the known bar mass in a free-weight total. Omitting the same bar every time can still show plate or rep progression, but the absolute load and percentage-based calculations will be wrong. Recheck the bar whenever equipment changes.
Why Counting the Bar Matters for Progress
Accurate overload: Progressive-overload training demands consistent tracking; skipping the bar hides real tonnage.
Program integrity: Most strength plans (e.g., 5×5, PHUL) assume you’re logging the full system weight.
Fair comparisons: Comparing lifts with friends or online peers works only when everyone includes the barbell weight.
Clear comparisons: If you change bars, record that change before interpreting the difference as progress.
At-Home & Specialty Bars
Building a home gym? Know your gear before you log:
Standard 1-inch barbell: “standard” often describes the plate-fitting diameter, not a standard mass. Confirm the particular bar’s unloaded weight and capacity.
Technique bar: Lightweight aluminum, perfect for mastering Olympic lifts.
EZ bars and curl bars: Angled grips may feel more comfortable than straight bars; check the particular weight and intended use.
Trap and hex bars: Neutral handles offer a different grip and loading position; comfort depends on the model and lifter.
Farmer’s-carry handles: Purpose-built implements for loaded carries; check the weight of each handle and log the load per hand.
Whatever tool you choose, record its empty weight in your workout app so you never second-guess your numbers.
FAQ
How much does a bench‑press bar weigh?
Common bench bars are 20 kg (44.1 lb) or labeled 45 lb (20.4 kg) models. Confirm the bar. A true 45 lb bar plus 45 lb on each side totals 135 lb; with a 20 kg bar and those same pound plates, the total is about 134.1 lb.
Is a Smith‑machine bar really 45 lbs?
Not necessarily. Counterbalanced machines can have much lower starting resistance than the bar’s physical mass. Read the exact model’s label or manual, ask staff if needed, and keep Smith-machine logs separate from free-weight lifts.
Key Takeaways
Bar weight: verify the label; 20 kg and 45 lb bars are both used in gyms and are not exactly equal.
Bench press: add the known bar weight to all plates on both sides.
Smith machine: record model-specific starting resistance, or clearly mark a plates-only convention if that resistance is unknown.
Should you count it? Absolutely—every rep, every set.
The Bottom Line
The bar is part of your free-weight lift. Identify it once, keep units consistent, and include it with both sides’ plates whenever you log a total.
Logging the Bar: Why Accurate Tracking Matters
An omitted bar creates a systematic undercount. If you always use the same bar, rep and plate progression can still be visible, but the absolute load and any percentage-based calculation will be wrong. Changing bars makes accurate identification especially important.
The simplest fix is to log the full system weight in a tracker so the bar is never an afterthought.

Does the Olympic bar weight include the collars?
The unloaded-bar specification excludes removable collars. IWF competition collars weigh 2.5 kg each, adding 5 kg per pair. Everyday collars vary by model; include their known mass if you need a precise total, and keep your logging convention consistent.
How much does a 7-foot Olympic bar weigh?
Length is a clue, not proof of mass. An IWF men’s bar is 2.2 m long and 20 kg. Other roughly seven-foot bars, including 45 lb power bars and 1-inch home-gym bars, can have different weights. Check the specification rather than estimating from length.
