Barbell collars, though often overlooked, are crucial pieces of equipment that prevent plates from sliding, ensuring stability, protecting you from injury, and enhancing your overall performance.

This article will cover everything you need to know about barbell collars, including the different types available, when and why to use them, detailed step-by-step instructions for application and removal, common mistakes to avoid, and essential safety tips. By the end, you'll be well-equipped to use them confidently and correctly in every training session.

Key Takeaways

• Barbell collars keep plates from shifting, improving stability and reducing accident risk.
• Use collars on most working sets, especially bench, overhead work, squats, deadlifts, and Olympic lifts.
• Match collar size to your bar sleeve: Olympic 2-inch 50 mm vs standard 1-inch 25 mm.
• Clamp style collars are the best all around choice for most lifters because they are fast and secure.
• Before heavy sets, do a quick tug test on each collar and plate stack to confirm nothing moves.

What Are Barbell Collars?

Barbell collars are simple but essential devices designed to hold weight plates firmly in place on a barbell. Their basic function is to prevent the plates from moving, shifting, or falling off the ends of the bar during an exercise.

You'll find barbell collars used in virtually every lifting environment, from home gyms to commercial fitness centers and professional weightlifting competitions. They are critical for maintaining balance and safety across various lifts.

It's important to note that collars are compatible with different types of barbells. Most commonly, you'll encounter Olympic barbells, which have a 2-inch (50mm) sleeve diameter, and standard barbells, which typically have a 1-inch (25mm) diameter. Specialty bars may have unique diameters, so always ensure your collars match the specific bar you are using.

Types of Barbell Collars

Not all barbell collars are created equal. Each type offers different levels of security, ease of use, and durability, making some more suitable for specific training styles.

Spring Collars

• Description and how they work: These are the most common and recognizable collars, featuring a simple spring-loaded mechanism. You squeeze two handles together to expand the coil, slide it onto the bar, and release to let the spring clamp down on the sleeve.
• Pros and cons: They are inexpensive and very quick to apply and remove, making them popular for circuit training or workouts with frequent weight changes. However, they offer less security than other types and can sometimes loosen during dynamic or heavy lifts.

Lock-Jaw / Clamp Collars

• Description and how they work: Also known as quick-release or clamp collars, these usually feature a plastic or metal body with a hinge and a locking lever. You open the lever, place the collar around the bar, and then close the lever to create a tight, secure clamp.
• Pros and cons: Lock-jaw collars are very secure and still relatively quick to use. They are more durable and provide a firmer hold than spring collars, making them a popular choice for most types of lifting. The main downsides can be a higher cost and the potential for some plastic models to crack over time.

Screw-Lock / Spin-Lock Collars

• Description and how they work: These collars are designed for threaded barbells (often standard barbells). You slide the collar onto the bar and then twist a screw or knob, which tightens the collar against the bar sleeve, creating a very secure fit.
• Pros and cons: Screw-lock collars offer exceptional security, virtually eliminating any plate movement. However, they are slower to apply and remove, which can be inconvenient for workouts requiring frequent weight changes. There's also a risk of over-tightening and potentially damaging the bar's threads if not used carefully.

Competition Collars (Olympic/Powerlifting)

• Description and typical use cases: These are specialized, highly precise collars used in Olympic weightlifting and powerlifting competitions. They are often heavier (e.g., 2.5 kg each for Olympic lifting) and designed for maximum grip and stability under extreme loads.
• Pros and cons: Competition collars provide the highest level of security and are built to withstand immense forces, meeting strict federation standards. They are very durable but also the most expensive and not typically necessary for general fitness training.

When You Should Use Barbell Collars

The short answer is: almost always. Barbell collars are a fundamental safety measure that should be part of your routine. Here’s a more detailed breakdown:

Lifts where collars are strongly recommended:

• Bench press: Prevents plates from sliding off if the bar tilts, which can cause severe injury.
• Overhead press: Essential for stability and preventing plates from shifting during dynamic overhead movements.
• Squats: Crucial for maintaining balance and preventing sudden weight shifts, especially when racking or unracking the bar.
• Deadlifts: Keeps plates snug, preventing them from rattling or sliding during powerful pulls and drops.
• Olympic lifts (Cleans, Snatches, Jerks): Absolutely vital due to the explosive and dynamic nature of these movements where plates can easily become dislodged.

Situations where collars might be optional or used with caution:

• Very light warm-up sets: While some may skip collars for very light warm-ups, it's generally a good habit to use them always to reinforce safety and consistency.
• Certain safety considerations when lifting alone (ability to dump plates): In rare cases, especially with squats when lifting alone and without safety spotters, some individuals might opt not to use collars. This allows for quickly "dumping" or shedding plates from the bar if a lift is failed and they need to escape from under the weight. However, this is a highly advanced consideration and comes with its own risks; for most, using collars is safer.

Keep in mind that most gyms and all official weightlifting and powerlifting competitions require the use of barbell collars for all working sets.

How to Use Barbell Collars: Step-by-Step

Properly using barbell collars is a simple process, but paying attention to the details ensures maximum safety and effectiveness.

General Preparation

1. Check barbell sleeve diameter and collar compatibility: Ensure your collars fit snugly on your barbell. Olympic collars for Olympic bars, standard collars for standard bars.
2. Inspect collars for damage or wear: Before each use, quickly check collars for cracks, bent springs, or worn-out mechanisms that could compromise their security.
3. Ensure plates have properly sized center holes: Worn plates with oversized holes might not be held as securely, even with collars.

Loading the Barbell Correctly

1. Place the bar on a stable rack or platform: This provides a secure base for loading.
2. Slide plates onto the bar evenly on both sides: Load plates symmetrically to maintain balance.
3. Ensure plates are fully seated against the inner collar/shoulder of the bar: There should be no gap between the first plate and the barbell's shoulder (the point where the sleeve meets the main shaft).

Applying Spring Collars

1. Stand to the side of the bar for control: This gives you a good angle for application.
2. Squeeze the handles to open the collar: Compress the spring until the collar opens wide enough to slide onto the bar.
3. Slide the collar onto the bar until it is firmly against the outermost plate: Push it all the way in so there's no gap between the collar and the plates.
4. Release pressure to let it clamp down: Allow the spring to close, gripping the barbell sleeve.
5. Check by pulling the collar and plates outward to confirm they don’t move: Give a gentle tug to ensure a secure fit.

Applying Lock-Jaw / Clamp Collars

1. Open the hinge or release lever: This expands the collar opening.
2. Position the collar around the bar, flush with the outermost plate: Ensure it's tight against the plates.
3. Close the lever until fully locked: You should feel a firm click or resistance, indicating it's secure.
4. Tug on the collar and plates to ensure a tight fit: Confirm there's no movement.
5. Adjust lever tension if needed: Some clamp collars allow you to fine-tune the tension for a tighter grip.

Applying Screw-Lock / Spin-Lock Collars

1. Slide the collar onto the bar: Place it over the threaded end of the barbell.
2. Turn the screw/knob to tighten against the bar sleeve: Rotate the collar until it is firmly pressing against the outermost plate.
3. Ensure it is snug without over-tightening or stripping threads: Tighten until secure, but do not force it past a comfortable resistance.
4. Check for any sliding during a test lift: A light, unweighted test lift can confirm the plates are secure.

Removing Barbell Collars Safely

1. Return bar to rack or floor with control: Always finish your set and safely put the bar down.
2. Release/twist/unscrew according to collar type:
   • For spring collars: Squeeze the handles.
   • For clamp collars: Open the lever.
   • For screw-lock collars: Unscrew the collar.
3. Remove collars before unloading plates, one side at a time with control: This prevents plates from unexpectedly sliding off or the bar becoming unbalanced.

Safety Tips and Best Practices

Beyond the basic steps, these practices will further enhance your safety and the longevity of your equipment:

• Always secure both sides of the bar: Never use a collar on only one side if plates are loaded on both. This creates an extreme imbalance and is highly dangerous.
• Avoid partially loaded bars with collars on one side only: If you are loading plates, ensure collars are ready for both sides.
• Double-check collars before each heavy set: A quick visual and physical check can prevent accidents.
• Don’t rely on friction or “tight plates” instead of collars: Even snugly fitting plates can loosen and slide during a lift.
• Special considerations when lifting alone (pros and cons of always using collars): As mentioned, advanced lifters might consider the "dumping" strategy for solo heavy squats without safety equipment, but this is an exception. For most lifts and lifters, especially alone, collars are a non-negotiable safety measure.
• Keep collars and bar sleeves clean and free of chalk or oil: Debris can reduce the grip of collars.

Common Mistakes to Avoid

Even with good intentions, simple errors can compromise the effectiveness of your barbell collars:

• Using collars that don’t match bar diameter: An Olympic collar on a standard bar (or vice-versa) won't fit or provide security.
• Leaving a gap between plates and collar: The collar must be flush against the outermost plate for maximum security.
• Forgetting collars during explosive lifts (cleans, snatches): The dynamic nature of these lifts makes collars absolutely critical.
• Over-tightening screw-type collars and damaging the bar or threads: Tighten until snug, not until the threads are stressed.
• Using damaged or cracked plastic collars: Compromised collars can fail mid-lift. Inspect regularly.

How to Choose the Right Barbell Collars for You

Consider these factors when selecting your collars:

• Training style: For powerlifting, prioritize maximum security (clamp or competition collars). For Olympic weightlifting, quick-release and strong grip are key. For general fitness, spring or clamp collars are usually sufficient.
• Bar and plate types in your gym: Ensure compatibility with the barbells you use most often.
• Budget and durability: Higher quality collars often last longer and provide better security.
• Ease of use and speed during workouts with many weight changes: If you frequently change weights, quick-release (spring or clamp) collars are preferable.
• Competition requirements (if applicable): If you compete, you might need specific types of approved collars.

Care, Maintenance, and Storage

A little care goes a long way in ensuring your collars remain effective and last for years:

• How often to inspect for cracks, bent springs, worn mechanisms: Make it a habit to quickly check collars before each use, or at least weekly.
• Cleaning recommendations (wiping down, avoiding harsh chemicals on plastic): A simple wipe-down with a damp cloth is usually enough. Avoid strong solvents, especially on plastic collars, as they can degrade the material.
• Where and how to store collars so they stay functional and easy to find: Store them on a designated hook, a small bin, or on the barbell itself. Avoid leaving them scattered on the floor where they can be stepped on or lost.

Quick FAQ on How to Use Barbell Collars

Do I need collars for every set?

Generally, yes. It's a good habit for safety, consistency, and to prevent plates from shifting even on lighter sets.

Are collars safe for bumper plates and deadlifts?

Absolutely. Even with bumper plates, collars prevent them from slowly sliding inward or outward during dynamic lifts like deadlifts, cleans, or snatches.

Can I mix different collar types?

It's not recommended. For optimal balance and security, use two identical collars. Different types might offer varying degrees of grip, leading to uneven plate retention.

What if my gym’s collars are loose?

Report it to the gym staff. If possible, use your own reliable collars, or seek out collars that provide a tighter fit. Never compromise on safety with loose collars.

Conclusion

Barbell collars are more than just an accessory; they are a vital component of safe and effective strength training. By understanding what collars are, how to properly apply and remove them, and the various types available, you empower yourself to lift with greater confidence and protection.

Always prioritize safety and consistency in your training. Make the habit of properly securing your barbell collars an integral part of every session. Your safety, stability, and performance depend on it.
