How Much Do The Small Barbells Weigh

If you’re setting up a home gym, you might be wondering how much do the small barbells weigh. Knowing the exact weight is crucial for planning your workouts and tracking progress. This guide will cover everything from standard sizes to how to choose the right ones for your fitness goals.

Small barbells are incredibly versatile. They are perfect for everything from shoulder presses to bicep curls. Understanding their weight helps you structure effective strength training sessions at home.

The weight of a small barbell depends on its type and intended use. There is no single answer, but common home gym barbells have predictable weight ranges. Let’s break down the most popular options you’ll encounter.

Standard Fixed-Weight Barbells

These are the most common small barbells in home gyms. They are a single piece of equipment with weights permanently attached at both ends. Their weights are clearly marked.

Lightweight Bars: Typically 5 to 15 pounds. Great for physical therapy, beginners, or high-rep arm work.
Medium Bars: Often 20 to 30 pounds. A good fit for most people doing curls, tricep extensions, and overhead presses.
Heavier Fixed Bars: Can range from 40 to 60 pounds. Used for more advanced lifters or exercises like bent-over rows.

Adjustable Spinlock Barbells

These bars have a central shaft and removable plates secured by spinlock collars. The weight changes based on the plates you add.

The bar itself usually weighs between 5 and 10 pounds.
You then add standard-sized plates (1, 2.5, 5, 10 pounds) to each side.
For example: A 6lb bar + two 5lb plates + two 2.5lb plates = a total of 21 pounds.

Olympic Technique Bars (Mini Version)

These are shorter versions of full Olympic bars, with the same 2-inch sleeve diameter. They are much less common in home gyms but are very sturdy.

They use Olympic plates (with a 2-inch hole), which start at 2.5 pounds each.

What About “Barbells” for Body Pump?

Group fitness classes often use very light, composite barbells. These are a special category.

They can weigh as little as 2 pounds
With plastic plates attached, they rarely exceed 20-30 pounds total.
They’re designed for high repetitions, not maximum weight.

How to Find the Weight of Your Specific Barbell

If the weight isn’t written on your bar, don’t guess. Here’s how to find out for sure.

Check for Markings: Look for numbers stamped or printed on the bar’s end cap or shaft.
Use a Bathroom Scale: Weigh yourself first, then weigh yourself holding the barbell. Subtract the first number from the second.
Check the Product Manual: If you still have it, the manual will list the bar’s specifications.
Contact the Manufacturer: The model number (often on the bar) can help the company tell you its exact weight.

Choosing the Right Weight for Your Home Gym

Selecting the correct barbell weight depends on your strength and your workout plan. Buying a set with multiple weights is often the best investment.

For Beginners

Start lighter than you think. Good form is more important than heavy weight.

A set with 10lb, 15lb, and 20lb bars is ideal.
An adjustable spinlock set with a light bar and small plates offers great flexibility.

For Intermediate Lifters

You’ll need a range to challange different muscle groups.

Consider fixed bars in 20lb, 30lb, and 40lb options.
A heavier adjustable bar (bar weight ~15lbs) with plates up to 50lbs total is a smart choice.

For Advanced Home Gym Users

You might need specialized bars, but small barbells still have a place.

Heavy fixed barbells (50-60lbs) for isolation work.
Multiple adjustable bars to avoid changing plates during circuit workouts.

Why Barbell Weight Accuracy Matters

Using the correct weight is not just about ego. It’s about safety and results.

Progressive Overload: To build muscle, you need to gradually increase resistance. Knowing the exact weight lets you track this.
Workout Consistency: If you use a 20lb bar one day and a 25lb bar the next thinking they’re the same, your workout data is inaccurate.
Injury Prevention: Jumping to a weight that’s too heavy because you misjudged it can lead to strains or worse.

Common Mistakes When Using Small Barbells

Even experienced lifters can make errors with this simple equipment.

Not Checking the Weight: Assuming all “short bars” are the same. Always verify.
Poor Collar Use: On adjustable bars, failing to secure the collars tightly can lead to plates sliding off mid-lift.
Using Imbalanced Weights: Putting a 5lb plate on one side and a 2.5lb on the other creates a dangerous imbalance.
Dropping Them: Small barbells are not meant to be dropped like heavy Olympic bars. It can damage floors and the bar itself.

Maintenance and Storage Tips

Taking care of your equipment ensures it lasts for years.

Wipe down the bar with a dry cloth after each use to remove sweat.
For chrome or steel bars, a light coat of oil occasionally can prevent rust.
Store them horizontally on a rack or vertically in a corner. Don’t let them lean against a wall, as they can fall.
Regularly check spinlock collars for thread wear and tighten them properly before every use.

What’s the best starter set for a home gym?

A spinlock adjustable barbell set with a ~6lb bar and about 50 pounds of plates is excellent. It gives you many weight options in a compact, affordable package. Alternatively, a pair of fixed-weight barbells (e.g., 15lb and 25lb) covers many basic exercises.
