What is a barbell?
A barbell is a long, sturdy metal rod designed to hold weight plates on either end. It serves as a cornerstone for various strength-training exercises, ranging from the classic squat and bench press to advanced lifts like the clean and jerk.
Barbells are preferred for their ability to allow progressive overload, a key principle in building strength and muscle.
Types of barbells and their standard weights
Barbells come in various types, each designed to suit specific exercises and lifters’ needs. Below is a detailed breakdown of the most common types, highlighting their unique features and applications.
Standard barbell
- Weight: Generally 9 kg (20 lbs) for men and 7 kg (15 lbs) for women, though this may vary.
- Length: Usually between 5 and 6 feet (152.4 to 182.88 cm).
- Diameter: Smaller and lighter than Olympic barbells.
- Usage: Perfect for beginners, home gyms, and lighter lifting routines. Standard barbells are commonly used for exercises such as curls, overhead presses, and light bench presses.
Standard barbells often have a fixed weight capacity, making them unsuitable for advanced lifters aiming for heavy loads.
Olympic barbell
- Weight: 20 kg (44 lbs) for men’s bars and 15 kg (33 lbs) for women’s bars.
- Length: 7 feet for men’s bars and around 6.5 feet for women’s bars.
- Diameter: Slightly larger, with 28 mm for men’s bars and 25 mm for women’s bars.
- Usage: Designed for Olympic lifts like the snatch and clean and jerk. Their rotating sleeves minimise torque on the wrists and elbows during dynamic movements.
Olympic barbells are standardised for competitions and are engineered for durability and performance under heavy loads.
Powerlifting barbell
- Weight: Standard 20 kg (44 lbs).
- Length: Similar to an Olympic bar but with less whip (it means the bar is stiffer and bends less; it’s less flexible).
- Key features: Thicker diameter and stiffer construction for stability during heavy lifts.
- Usage: Ideal for squat, bench press, and deadlift. Powerlifting barbells are built to withstand extremely heavy weights without bending.
- Knurling: Features aggressive knurling to improve grip during maximal lifts.
Here is a summary table comparing the Olympic barbell and the powerlifting barbell.
| Feature | Olympic Barbell | Powerlifting Barbell |
|---|---|---|
| Flexibility (whip) | High (more flexible) | Low (Stiffer) |
| Knurling | Medium, no centre knurl | Aggressive, often with centre knurl |
| Sleeve Rotation | Fast, with bearings/bushings | Slower, with bushings |
| Diameter | 28 mm (Men), 25 mm (Women) | 29 mm |
| Weight | 28 mm (Men), 25 mm (Women) | 20 kg |
| Load Capacity | High (dynamic lifts) | Extremely High (static lifts) |
| Usage | Olympic lifts, CrossFit | Powerlifting competitions |
Trap bar (hex bar)
- Weight: Ranges between 11 and 20 kg (25–45 lbs), depending on the design.
- Shape: Hexagonal, allowing you to stand inside the bar.
- Usage: Great for deadlifts, shrugs, and farmer’s carries. Its ergonomic design places less strain on the lower back and shoulders, making it ideal for beginners and injury-prone lifters.
- Bonus benefit: The neutral grip reduces stress on the wrists compared to traditional barbells.
EZ curl bar
- Weight: Typically between 7 to 11 kg (15–25 lbs).
- Design: Curved shape for a more natural hand positioning.
- Usage: Best suited for arm-focused exercises like bicep curls and tricep extensions. The wavy design reduces strain on the wrists, making it a favourite for those with wrist issues.
Safety squat bar (SSB)
- Weight: Heavier than standard barbells, typically around 27 to 32 kg (60–70 lbs).
- Design: Includes padded neck and shoulder support, with handles extending from the bar.
- Usage: Ideal for lifters who have shoulder mobility issues or need an upright squat position. It shifts the centre of gravity slightly forward, engaging the quads more than traditional back squats.
Speciality bars
Speciality bars are uniquely designed for specific training purposes, offering versatility and variety to your workouts. They are often used to target particular muscle groups, accommodate unique grips, or address individual lifting needs that standard barbells may not cover.
Speciality bars vary significantly in weight, ranging from 7 to 32 kg (15–70). Their weight depends on the design and intended purpose, with some bars being lighter for functional exercises and others heavier for advanced training.
Some examples of the speciality bars are described below.
Cambered bars
Feature a curved design to reduce shoulder strain during squats or to create a different range of motion for bench presses and more.
Axle bars
Also known as fat bars, they have a thicker grip to enhance forearm and grip strength, making them a favourite for strongman training.
Swiss bars (or multi-grip bars)
Come with multiple neutral grip options, allowing lifters to alleviate wrist and shoulder stress while targeting specific upper body muscles during presses or rows. They could be perfect for athletes recovering from injuries or those looking to diversify their pressing exercises.
How to Identify barbell weight
Sometimes, identifying the weight of a barbell can be tricky. Here’s how to ensure accuracy:
- Inspect the bar: Many barbells have the weight engraved on their end caps or along the shaft.
- Check gym guidelines: Commercial gyms often provide details about their equipment.
- Use a scale: If in doubt, place the barbell on a reliable scale to confirm its weight.
Factors influencing barbell weight
Several factors determine the weight of a barbell:
- Material: Higher-quality steel or alloy barbells tend to be heavier and more durable.
- Length and diameter: Longer and thicker bars naturally weigh more.
- Load capacity: Bars designed to hold heavier weights are often reinforced and therefore heavier.
Why barbell weight matters
For a passionate weightlifter, knowing the barbell weight is essential for two key reasons:
Programming and accurate load calculation
Understanding the exact weight of the barbell ensures that you can calculate the total weight you’re lifting with precision. This is especially important for tracking progress, maintaining proper training intensity, and meeting specific strength or hypertrophy goals.
Safety and technique
Being aware of the barbell’s weight allows you to choose an appropriate load that aligns with your strength level and the exercise you’re performing. This helps prevent overloading, which could lead to compromised technique and increased risk of injury.
You can also avoid overloading a bar beyond its capacity, which can lead to equipment failure.
Maintenance tips for longevity
With consistent maintenance, your barbell can stay in excellent condition for years, providing you with safe and reliable performance. Here’s how to keep your barbell in top condition:
Regular cleaning
After every use or at the end of the day, wipe down the bar with a clean, dry cloth to remove sweat, chalk, and dust. For stubborn debris or buildup, use a stiff nylon brush to clean the knurling without damaging the finish.
Protect against rust
Store your barbell in a dry, well-ventilated area to prevent rust from forming, especially if you live in a humid climate. Applying a light coat of oil (such as 3-in-1 oil) every few months can provide an additional layer of protection against moisture.
Inspect rotating sleeves
For Olympic barbells, regularly check that the sleeves rotate smoothly. Clean and lubricate the sleeves and bushings or bearings as needed to prevent stiffness, which can affect performance during lifts.
FAQs about barbell weights
-
What’s the difference between men’s and women’s Olympic barbells?
Women’s Olympic barbells are shorter, lighter, and have a smaller diameter for a better grip. Both are designed with high durability and rotating sleeves.
-
Can I use an Olympic barbell for powerlifting?
Yes, but a dedicated powerlifting barbell offers better stability and grip for heavy squats, bench presses, and deadlifts due to its stiffer construction.
-
Why do some bars have different knurling patterns?
Knurling patterns provide grip. Aggressive knurling is for heavy lifts, while milder knurling suits lighter lifts or high-rep training.
-
How do I know if my barbell is bending?
A bent barbell may not spin evenly when rotated. If the bend is noticeable or affects performance, it’s time to replace it.
