How Much Does a Weightlifting Bar Weigh: Essential Facts for Lifters


Weightlifting is essential to many fitness routines, providing numerous health benefits and the potential to increase your strength and muscle mass.

As you begin your weightlifting journey, you may wonder about the different types of weightlifting bars and how much they weigh.

Knowing the exact weight of the bar you’re using will allow you to accurately track your progress, ensuring that you’re lifting appropriate amounts for your goals and abilities. By staying informed, you’re setting yourself up for success in your weightlifting endeavors.

Types of Weightlifting Bars

Here are the types of weightlifting bars you can lift.

Olympic Barbell

When it comes to weightlifting bars, the Olympic barbell is likely the first type that comes to your mind. These bars are seven feet long and weigh twenty kilograms (forty-four pounds). They have a gripping surface around twenty-eight to thirty mm in diameter, with rotating sleeves at the ends for smooth weight plate loading.

Standard Barbell

Your gym might also have standard barbells, usually shorter (five to six feet long) and lighter (fifteen to twenty-five pounds) than Olympic barbells. The main difference lies in the diameter, typically around an inch, and the non-rotating sleeves.

Trap or Hex Bar

Trap or hex bars feature a unique design with a hexagonal frame that you can stand inside while lifting. This shape changes your hand position to make the lift more comfortable on your spine. Hex bars usually weigh thirty to sixty pounds and come in various lengths.

Safety Squat Bar

A safety squat bar reduces strain on your shoulders and upper back by changing the lifting mechanics. It has a padded bar with handles, allowing you to lift heavier weights safely. This type of bar typically weighs around twenty-five to thirty kilograms.

EZ Curl Bar

An EZ curl bar has an angled design, allowing for improved wrist comfort during bicep curls and tricep extensions. These bars are shorter and lighter than standard barbells, weighing ten to twenty-five pounds.

Swiss or Multi-Grip Bar

Swiss or multi-grip bars have various handle configurations, allowing for different pressing and rowing exercises with neutral grip positions. These bars can weigh anywhere from thirty to sixty pounds, depending on the size and material used.

Women’s Barbell

Women’s barbells are similar to Olympic barbells but lighter and smaller in diameter. The standard women’s barbell is 6.5 feet long, weighs fifteen kilograms (thirty-three pounds), and has a twenty-five mm gripping surface.

Smith Machine Bar

Lastly, the Smith machine bar is a unique barbell that moves vertically within a fixed track system during squats and bench presses. Unlike free-weight barbells, the Smith machine bar provides added stability and safety, weighing around fifteen to twenty-five pounds.

Knowing the differences among these weightlifting bars can help you find the right tool to meet your specific fitness goals and needs.

Bar Specifications

The specifications of a bar consist of the weight and thickness, knurling patterns, whip and bearing, and center knurling.

Weight and Thickness

In general, weightlifting bars vary in weight and thickness. Men’s Olympic bars usually weigh around twenty kg (forty-four lbs), while women’s Olympic bars weigh around fifteen kg (thirty-three lbs). Men’s bars typically measure twenty-eight mm, and women’s bars have a slightly smaller diameter at twenty-five mm. Here are some common bar types and their weights:

  • Men’s Olympic Bar: 20kg (44lbs), 28-29mm diameter
  • Women’s Olympic Bar: 15kg (33lbs), 25mm diameter
  • Training Bar: 10kg (22lbs), 25-28mm diameter

Knurling Patterns

Knurling is an essential aspect of a weightlifting bar, providing a grip for the lifter. There are different patterns you probably can find on your bar:

  • Diamond-shaped: Provides an aggressive grip.
  • Straight lines: Offers moderate grip, widely used
  • Milled pattern: A fine grip ideal for high-rep workouts

Whip and Bearings

Whip refers to the flexibility or oscillation of the bar when it bends under heavy loads. Bearings, however, are responsible for the smooth rotation of the sleeves. Competition-level bars offer better whip and quality bearings for consistent performance. The whip can be categorized as follows:

Center Knurling

Center knurling provides extra grip when the bar is placed on the lifter’s back during squats. Some bars include a center knurl, while others don’t. Generally, powerlifting and squat bars have center knurling, while Olympic lifting and training bars might not.

When choosing your weightlifting bar, consider these factors and make an informed decision based on your personal preferences and the type of lifting you engage in.

Common Exercises and Barbell Use

Here are the common exercises you can do with barbells.

Deadlifts and Squats

Deadlifts and squats are essential exercises for strength and muscle development. They both require the use of a barbell. Standard Olympic barbells weigh twenty kg (forty-five lbs), and the weights you add to each side will depend on your strength level.

You will start with the barbell on the floor, standing parallel to it for deadlifts. Then, bend at the hips and knees to grip the bar and lift it off the ground by fully extending your hips and knees.

You will need a squat rack to hold the barbell at the appropriate height for squats. Set up the barbell at chest height and step under it, positioning the bar on your upper back. To perform a squat, lower your body by bending at the knees and hips, keeping your chest up, and maintaining a neutral spine.

Bench Press and Overhead Press

These are vital exercises for building upper body strength. Both of these exercises utilize a barbell. As with deadlifts and squats, an Olympic barbell is typically used, weighing twenty kg (forty-five lbs).

Lie on a flat bench with your feet planted firmly for bench presses. Grip the barbell with your hands slightly wider than shoulder-width apart, then lower the bar to your chest before pressing it back up to the starting position.

In contrast, the overhead press challenges your shoulder muscles. While standing, grip the barbell slightly wider than shoulder-width apart. Rest the bar on your upper chest, and press it overhead until your arms are fully extended before lowering it back to the starting position.

Cleans and Snatches

Cleans and snatches are explosive Olympic lifts that develop total body strength and power. These movements require precise technique and the use of an Olympic barbell, which weighs twenty kg (forty-five lbs).


Cleans involve lifting the barbell from the ground to your shoulders swiftly, while snatches require lifting the barbell from the floor to an overhead position in a single, continuous movement. Both exercises require speed, coordination, and strength.

Biceps Curls and Triceps Extensions

Biceps curls and triceps extensions are isolation exercises that target the biceps and triceps, respectively. You can use an Olympic barbell or a lighter, smaller barbell, such as an EZ curl bar, typically weighing around seven to ten kg.

Stand with your feet shoulder-width apart for biceps curls and hold the barbell with an underhand grip. Curl the bar up by flexing your elbows and forearms until your biceps are fully contracted, then return to the starting position.

Triceps extensions are performed by holding the barbell with an overhand grip at shoulder level. Extend your arms overhead to focus on your triceps muscles, then slowly lower the bar behind your head.

Remember to practice proper form consistently and gradually increase weight as you become more robust to maximize the benefits of these exercises.

Training and Performance Considerations

When incorporating weightlifting bars into your strength training, it’s essential to consider their weight and how it impacts your performance. Different bars have distinct purposes and suit specific exercises like deadlifting, CrossFit, and compound movements.

Regarding training, a standard barbell weighs around twenty kg (forty-four lbs) for men and fifteen kg (thirty-three lbs) for women. These bars are ideal for squats, bench presses, and deadlifts. You may opt for specialized bars with specific weights and designs for a more diverse range of exercises and sports, such as CrossFit and Olympic lifting.

To optimize your training regimen, pay attention to the following aspects:

In addition to weightlifting bars, consider incorporating various accessories into your training, such as:

  • Safety collars: Secure the weights and prevent them from slipping off the bar.
  • Weight plates: Adjustable plates allow you to change the bar’s weight to suit your needs.
  • Squat racks: Provide stability, safety, and support for compound movements like squats and bench presses.

Remember that different sports demand specific performance goals. In competitive strength sports, athletes need to focus on lifting maximum loads. Conversely, CrossFit and other functional fitness disciplines emphasize performing a diverse range of movements with speed and efficiency.

By taking the weight and type of weightlifting bar into account, reps, technique, and progression, you can create a more efficient and effective strength training program that caters to your personal goals and improves overall performance.
