In today's ever-evolving industry, understanding the importance of custom barbell is crucial for staying competitive and making informed decisions. This article explores custom barbell, offering practical insights for businesses and professionals alike.

When it comes to strength training and Olympic lifting, having the right barbell is crucial. Olympic barbells are specifically designed to withstand heavy loads and provide optimal performance during various exercises. In this comprehensive guide, we will explore their features, variations, and which one might be the perfect fit for your training needs.

So you come to our website, you see a huge range of different barbells. You can see that we have men’s, women’s, specialised, beginner’s  and cerakote barbells. Let’s say you want a 20kg barbell, so you go to the men’s category, but you get lost in all the specifications. Don’t worry, we’re here to help you. After reading this blog you will know all the differences. Now, let’s dive into the different types of Olympic barbells and their specifications.

Different use, different types of barbell

  • Powerlifting Barbells:

If you prioritize heavy lifting and strength-focused workouts, Kingsbox powerlifting barbells are ideal. With a more rigid construction and higher weight capacity, they provide stability and support for intense powerlifting movements like squats, deadlifts, and bench presses. They are made from more rigid steel, the Knurl Marks are spaced closer together and the diameter is wider.

  • Weightlifting Barbells:

KingsBox weightlifting barbells are specifically designed for Olympic weightlifting movements, such as the snatch and clean and jerk. They feature more whip and spin to facilitate explosive lifts, allowing for better performance and technique. The steel is more elastic; this way the bar can bend more and have a better “Whip” to it.

  • Hybrid Barbells:

Are suitable for a wide range of strength training exercises. They blend the characteristics of both powerlifting and weightlifting barbells, offering a balanced design that caters to multiple fitness goals. They have dual marks, the weightlifting and powerlifting marks.

  • Beginner Barbells:

For those who are new to weightlifting or strength training, Kingsbox offers beginner barbells with a lighter weight and more forgiving specifications. These barbells provide a comfortable grip and are designed to help users develop proper form and technique.

  • Specialized Barbells:

Kingsbox specialized barbells cater to specific training needs. Whether you’re focused on training for CrossFit, Strongman competitions, or other specialized disciplines, these barbells offer unique features and specifications tailored to your requirements.

Coating Types

We offer a variety of coatings for the barbells, each with its own unique characteristics. Let’s explore some of the most common coating options:

  • Black Zinc: Provides corrosion resistance and durability. Quite good protection but quickly lose its shine.
  • Hard Chrome: Offers a smooth, hardened surface with excellent corrosion resistance.
  • Cerakote: Known for its exceptional durability, scratch resistance, and vibrant color options.
  • Titanium: Lightweight and incredibly durable, suitable for high-performance lifting.
  • Powder Coating: Provides a textured finish for enhanced grip and durability.
  • Cataforesis: A corrosion-resistant coating that ensures long-lasting protection

Knurling and Knurl Marks

Knurling refers to the textured pattern on the barbell’s grip area. Kingsbox offers different types of knurling to suit various preferences:

  • Fine Knurling: Provides a less aggressive grip, suitable for those who prefer a smoother feel during lifts.
  • Medium Knurling: Strikes a balance between grip and comfort, offering moderate aggression for most lifters.
  • Aggressive Knurling: Delivers maximum grip for advanced lifters and those who prefer a more secure hold.

Additionally, some Kingsbox barbells feature central knurling, which provides extra grip during movements that involve resting the barbell on the body, such as squats. The Hybrid Bars come without central knurling. That is because the hybrids are designed for functional and cross-training where high repetition sets of exercises are the norm. Athletes doing high reps could hurt their knees or sheens if there was a central knurling.

Tensile Strength

Tensile strength refers to the maximum amount of weight a barbell can withstand before it permanently bends or breaks. The tensile strength test is a process that tests how much pressure it takes for a barbell to deform permanently. It is measured in Pounds per Square Inch (PSI).

Kingsbox barbells come in different tensile strength ratings, allowing you to choose the appropriate level of durability for your training intensity.

Good quality barbells start at 165.000 PSI. When the PSI goes above 190.000 we start talking about supreme-quality barbells. The rule is: the higher the PSI, the higher the price.

180.000 PSI: QUEENS BAR OLYMPIC BARBELL (217,31€)

190.000 PSI: KINGS BAR II. OLYMPIC BARBELL (242,78€)

195.000 PSI: THE C BAR – WOMEN’S OL BARBELL (298,9€)

205.000 PSI: GOLD BAR (336,72€)

215.000 PSI: ROYAL WL BAR II. (771,65€)

Choosing the Right Barbell for You

Now that we’ve explored the different types, coatings, knurling, and tensile strength, let’s recommend five Kingsbox barbells suitable for various fitness goals:

  • EUROPE BAR

This is a hybrid barbell for all types of training. Whether you plan on weightlifting or powerlifting, this barbell will serve its purpose. It is made from high quality steel and coated in durable hard chrome. You can get it at a very affordable price.

  • ROYAL WL BAR II.

If you prefer weightlifting and you’re looking for a special and excellent barbell, this is the one for you. It is made from the highest quality steel for the most demanding athletes. That’s why it’s a little more expensive.

  • UNDERGROUND POWER BAR

Of course we need to highlight the best powerlifting barbell too. It is perfect for performing squats, bench press and dead lifts, where knurl marks ensures a good grip. The central part is coated in black zinc while the sleeves are chromed. The bar also has central knurling.

  • EUROPE BAR CERAKOTE – BUSHING SERIES

Again, if you’re looking for a good hybrid barbell at an affordable price, but you’re also a visual person and matching outfits with your barbell means a lot to you, cerakote bars are for you. In addition to the Europe bar, you can also find a Kings or Queens bar.

  • KINGS BAR II. OLYMPIC BARBELL

It would be a sin not to mention and recommend this one. It is the top selling barbell. Why is it a bestseller? For a very reasonable price you can get a good quality hybrid barbell. It has four needle bearings that ensure smooth and uninterrupted rotation. It is made of steel with high flexibility and durability (190,000 PSI) and is covered with a hard-chrome coating that protects against external factors.

The top 6 barbells for a home gym are:

  • Competition Barbell - Best Barbell Overall
  • Olympic Barbell - Best Barbell for Olympic Lifting
  • Power Barbell - Best Barbell for Powerlifting
  • Axel Bar - Best Barbell for Strongman
  • SSB Bar - Best Speciality Barbell
  • EZ Bar - Best Barbell for Accessory Training

Competition Barbell - Best Barbell Overall

  • Weight: 20 kilograms or 44 pounds
  • Length: 86.75 inches
  • Diameter: 28.5 mm
  • Knurling: Medium with Dual Marks and No Center Knurl
  • Loadable Sleeves: 16.4in

This is a special bar built by Iron Bull Strength that is a cost-effective bar that will fulfill all of your weightlifting needs. The dual knurl marks provide a secure hold for Olympic lifts, while the smooth rotating sleeves allow for flawless movement execution. Not only is our barbell built to last, but it’s also versatile enough for a wide range of exercises.

This competition barbell by Iron Bull Strength can help you prepare for competition as it can function for all types of weight lifting programming, such as Olympic lifting or powerlifting. This would be a great barbell to meet all your needs with your own home gym.

Olympic Barbell - Best Barbell for Olympic Lifting

  • Weight: 20 kilograms or 45 pounds
  • Length: 86 inches
  • Diameter: 28-29mm
  • Knurling Strength: Medium
  • Loadable Sleeve: 16 inches

The Olympic barbell is designed specifically for dynamic movements such as the power clean and push press. The Olympic barbell is built with rotating sleeves to help meet the needs of all types of explosive movements you would experience with Olympic lifts. The bar is slightly rigid, but still provides a bend or “whip” to accommodate the explosiveness of Olympic lifts. With a length of 86 inches and medium knurling, it’s a standard choice for Olympic weightlifting movements. This barbell could be used for the big three movements like the squat, bench, and deadlift. However, a barbell with more aggressive knurling might be ideal for these stronger movements to help maintain grip and positioning during each lift.

Power Barbell - Best Barbell for Powerlifting

  • Weight: 45 pounds
  • Length: 86 inches
  • Diameter: 28-30mm
  • Knurling Strength: Aggressive
  • Loadable Sleeve: 16 inches

The power bar is a variation of the traditional straight barbell but much more stiff and rigid to not bend under pressure, especially in powerlifting. The idea is that with stronger movements like the squat, bench press, and deadlift, you want a stronger bar to counterbalance the movement and feel more capable of your own strength. It also features aggressive knurling to improve grip when lifting heavier loads. This barbell would not be idea for those who do Olympic lifts as this bar is resistant to bending and has an aggressive knurling that could cause damage to the skin during dynamic movement.

If you are looking to get a great power bar, try out Iron Bull’s Zinc Power Bar. This power bar features a deep and coarse powerlifting knurling pattern providing an ideal grip without being sharp or abrasive, preventing the bar from slipping under heavy loads. The sleek finish not only adds a touch of elegance to your gym setup but shields your barbell against corrosion and oxidation, extending its lifespan and performance over time.

Axel Bar - Best Barbell for Strongman

  • Weight: 20-45 pounds
  • Length: 80-86 inches
  • Diameter: 48-50mm
  • Knurling: None
  • Loadable Sleeve: 15-16 inches

A unique choice for strongman training, the axel bar has a larger diameter and ranges between 20-45 pounds. It challenges grip strength and is commonly used in strongman competitions. Axel bars may not have the same rotating sleeves as other bars which makes it very challenging to use. This is a great barbell to meet the needs of many strongman events. I would not recommend this barbell to anyone who doesn’t do strongman as the features of this barbell don’t suit most traditional movements in strength training.

SSB Bar - Best Speciality Barbell

  • Weight: 45-65 pounds
  • Length: 86-92 inches
  • Diameter: 40-43 mm (handles)
  • Knurling: None
  • Loadable Sleeve: 15-16 inches

The squat safety bar (SSB) is a great specialty bar to help your training, especially on leg day. It is ideal for individuals with shoulder mobility issues or those looking to target their lower body without compromising form. The SSB bar features unique shoulder pads that distribute weight evenly, reducing strain on the shoulders and upper back during squats. However, the SSB does put weight higher on the torso, so it is a challenge for your postural muscles the heavier you get. You can also train unique exercises with the SSB bar like the Hatfield Squat, which reduces recruitment of those postural muscles and starts to massively overload the leg muscles.

EZ Bar - Best Barbell for Accessory Training

  • Weight: Around 25 pounds
  • Length: 46-48 inches
  • Diameter: 28 mm
  • Knurling: Light - Medium
  • Loadable Sleeve: 6-8 inches

The EZ bar is a uniquely designed bar that allows more comfort with accessory exercises that relate to upper body muscle groups like the biceps and triceps. This is a great accessory tool that will help you overload your anatomy without having to use a length straight bar or having to own a series of weighted dumbbells that might take space with your home gym set up.

Benefits to a Home Gym Barbell

Some of the biggest benefits to having a home gym barbell are:

  • Strength development
  • Muscular hypertrophy
  • Versatility

Strength Development

Barbells allow for compound movements that engage multiple muscle groups simultaneously, promoting functional strength development. Exercises like squats, deadlifts, and bench presses require coordination, balance, and core stability, translating to improved performance in daily activities and sports.

Muscle Hypertrophy

Barbells provide an effective means of stimulating muscle growth. By lifting heavy weights with proper form and progressively overloading the muscles, individuals can trigger hypertrophy, leading to increases in muscle size, strength, and definition.

Versatility

With a barbell, you can perform a wide range of exercises targeting various muscle groups. From classic compound lifts like squats, deadlifts, and rows to isolation exercises such as bicep curls and tricep extensions, the versatility of barbell training enables you to create diverse and effective workout routines.

How to Choose the Right Home Gym Barbell

In order to choose the right barbell, you need to:

  • Identify training goals
  • Evaluate exercise selection
  • Training intensity

Identify Your Training Goals

Before purchasing a barbell, clarify your fitness objectives and the type of exercises you plan to perform. Are you primarily focused on powerlifting, weightlifting, bodybuilding, or general strength training? Understanding your goals will help narrow down the options and determine which type of barbell is most suitable for your needs.

Evaluate Exercise Selection:

Pay attention to key specifications such as bar length, diameter, weight capacity, and knurling. Standard Olympic barbells typically measure 7 feet in length and have a diameter of 28-29mm, while powerlifting bars may be shorter and thicker with more aggressive knurling for better grip. Choose a barbell with appropriate specifications based on your body size, lifting style, and comfort preferences.

Training Intensity

The sleeves of a barbell should rotate smoothly to reduce friction and wrist strain during lifts. Look for barbells equipped with quality bearings or bushings that facilitate effortless sleeve rotation, allowing for smoother and more controlled movements.

Taking Care of Your Home Gym Barbell

Proper maintenance is essential to prolong the lifespan and performance of your barbell and ensure safe and effective workouts. Here are some tips for taking care of your barbell:

  • Clean Regularly: After each use, wipe down the barbell with a clean, dry cloth to remove sweat, chalk, and debris that can accumulate on the shaft and sleeves.
  • Inspect for Damage: Regularly inspect your barbell for signs of wear, damage, or defects, such as bent shafts, loose sleeves, or worn knurling. Knowing when these occur can help you reduce future damage.
  • Store Properly: Store your barbell in a dry, climate-controlled environment away from moisture, humidity, and extreme temperatures. Use barbell storage racks or horizontal holders to keep the barbell upright and prevent warping or bending.
  • Lubricate Sleeves: Apply a thin layer of barbell lubricant or oil to the sleeves periodically to maintain smooth rotation and reduce friction.
  • Avoid Dropping: Minimize dropping or slamming the barbell on hard surfaces, as this can cause damage to the shaft, sleeves, and internal components. Use bumper plates or lifting platforms to absorb impact and protect the barbell during heavy lifts and drops.

Conclusion

In conclusion, selecting the best barbell for your home gym is a pivotal decision that can significantly impact the effectiveness and enjoyment of your workouts. Whether you’re focused on powerlifting, Olympic lifting, strongman training, or accessory exercises, there’s a barbell tailored to meet your specific needs and goals. From the versatile Competition Barbell to the specialized SSB Bar and EZ Bar, each option offers unique features and benefits that enhance strength development, muscle hypertrophy, and overall versatility in your training routine.

Moreover, proper maintenance and care are essential to ensure the longevity and performance of your barbell investment. By regularly cleaning, inspecting for damage, storing appropriately, lubricating sleeves, and minimizing impacts, you can preserve the integrity of your barbell, preventing premature wear and tear while promoting safe and effective workouts. With the knowledge gained from this guide, you’re equipped to make an informed decision in selecting the perfect barbell to elevate your home gym experience and take your fitness journey to new heights.

Whether you're looking to improve efficiency, reduce costs, or stay ahead in the market, barbell custom can offer significant value, and you can make better choices tailored to your specific needs.
