Other Types of Bars and Their Weights
Not all bars are the same, and it’s important to recognize the differences when you’re in the gym. Here are some other types of bars you might encounter:
Women’s Olympic Barbell

When I first used a friend’s Smith machine, I assumed the bar was 45 pounds. To my surprise, it was only 25 pounds!
How to Figure Out the Bar’s Weight
So, how do you know what the bar weighs? It’s easier than you think:
Look for Markings
Many bars have the weight stamped on the end, such as “45 lbs” or “20 kg.” Always check for this marking.
Ask Someone
If you’re unsure, ask the gym staff or fellow lifters for help. They can quickly tell you the weight.
Weigh It
If you have a portable scale, you can check the bar’s weight yourself. This is especially useful if the markings are unclear or worn off.
Trust Your Senses
I once used a bar that I thought was 45 pounds, but it turned out to be 25 pounds. Now, I always check the markings before starting my workout. Click Here: Bench Press: Master the Basics
Tips for Double-Checking the Weight

Even if you think you know the bar’s weight, it’s always good to double-check:
- Olympic bars usually weigh 45 pounds, but it’s always a good idea to double-check.
- Smaller or thinner bars often weigh less than Olympic bars.
- Smith Machine bars can be tricky check the machine’s label to avoid surprises.
I learned the hard way after using a Smith machine bar, thinking it was 45 pounds. In reality, it was only 20 pounds due to a counterbalance system.

Common Mistakes People Make with Bar Weight
It’s easy to make mistakes when tracking your lifts. Be aware of these common errors:
- Forgetting to add the bar’s weight: Make sure you account for the weight of the bar itself before adding plates.
- Assuming every bar is 45 pounds: Not all bars are the same weight, so verify it first.
- Ignoring the collars: The clips (collars) holding the plates in place add a little weight too—don’t forget them!
For example, if you’re using a 45-pound bar and add two 45-pound plates on each side, your total weight lifted would be 135 pounds. Make sure to factor in everything!
Why Gyms Use Different Bars
Not all gyms have the same setup. Here’s why:
- High-end gyms tend to use top-quality Olympic bars.
- Older or smaller gyms may have lighter, standard bars.
- Specialty gyms may have powerlifting or specific training bars, each with its own weight and function.
In one gym I visited, the Olympic bar felt lighter due to wear and tear. It’s always good to ask or check if the weight feels off. Get More: Bench Press: Strength Starts Here
Parts of the Bar That Affect Weight

A bench press bar isn’t just a simple stick of metal it has several components that contribute to its weight:
- Shaft: The long middle part that you hold.
- Sleeves: The ends where the weight plates go.
- Knurling: The rough texture for grip.
- Collars: The clips that secure the plates.
Each part plays a role in the overall weight and functionality of the bar, so understanding these components is key.
How Bar Weight Affects Your Training Goals
Understanding the weight of your bar helps you set achievable goals. Here’s how average lifters might approach the bench press with a 45-pound Olympic bar:
- Beginner: 103 pounds (bar + plates)
- Intermediate: 217 pounds (bar + plates)
- Advanced: 291 pounds (bar + plates)
Teenagers may start with lighter bars. For example, a 14-year-old could begin with a 25-pound bar and build up from there.
