The science behind weightlifting belts

Weightlifting belts have long been a topic of interest in the realm of strength training, with studies highlighting their potential benefits and drawbacks.

A study by Kingma et al. (2006) in the Journal of Biomechanics demonstrated that wearing a weightlifting belt during lifting can increase intra-abdominal pressure by up to 40%, which in turn provides substantial support to the lower back by enhancing the stability of the spine (1). This biomechanical advantage is critical during heavy lifts, as it can reduce the shear forces acting on the spine, thereby lowering the risk of injury.

Moreover, research published in the Journal of Strength and Conditioning Research (Zink et al., 2001) found that athletes who used weightlifting belts could see an increase in their maximal lifts by 5-15%, a significant boost that could be particularly beneficial in competitive settings or for personal achievement (2).

This improvement in performance is attributed to the increased intra-abdominal pressure that aids in stabilizing the spine during heavy lifts, allowing for greater force production.

Despite these benefits, the use of weightlifting belts is not without its drawbacks. Over-reliance on belts may lead to a potential underdevelopment of the body's natural core musculature.

As McGill (2015) points out, continuous use of weightlifting belts during all lifting activities can result in the core muscles becoming less engaged, potentially diminishing the body's natural ability to stabilize the spine (3).

Furthermore, improper use of belts, such as fastening them too tightly or using them for inappropriate exercises, can hinder movement patterns and breathing, thereby detracting from the lift's effectiveness and safety.

Practical tips for using weightlifting belts

Know when and how to use it

It's important to use weightlifting belts strategically. They are most beneficial for lifts that place a substantial load on the lower back, like squats, deadlifts, and overhead presses.

The key is to engage the core and "push" against the belt during these exercises, which enhances the stabilization of the spine by further increasing intra-abdominal pressure.

Ensuring a proper fit

A snug fit is crucial for a belt's effectiveness. It should be tight enough to provide substantial support but not so tight that it compromises your ability to breathe deeply or execute the lift properly.

Tips for beginners and new users

For beginners, integrating a weightlifting belt into your training regimen should be a considered decision based on your training progress, goals, and the development of foundational strength and technique.

Develop core strength first

  • Focus on Technique: Before relying on a belt, beginners should prioritize learning proper lifting techniques and building core strength through foundational exercises such as planks, squats, and deadlifts without a belt.

  • Progressive Overload: Gradually increase the weight you lift over time to naturally strengthen your core muscles and improve overall stability.

When to consider a belt

  • Reaching Intermediate Levels: Once you have developed a solid foundation of strength and are lifting weights close to or above your body weight, particularly in exercises like squats and deadlifts, it might be time to consider a belt for added support and safety.

  • Listen to Your Body: If you start experiencing stability issues or minor strains in your lower back as you progress to heavier lifts, a belt can offer the extra support needed to safely continue advancing.

How to choose the right weightlifting belt

When selecting a weightlifting belt, particularly for general strength training, several factors come into play, including material, width, thickness, and closure system.


Leather belts are preferable for their durability and support. Nylon belts might offer more comfort and flexibility but generally provide less support.


A consistent four-inch width is ideal for most lifters, offering ample support around the waist.


A belt with a thickness of about 10mm is suitable for general strength training, offering a good balance of support and flexibility.

Closure system

Prong closures are reliable and allow for a custom fit, while lever closures offer ease of use with quick adjustments.

Putting it into action

While weightlifting belts offer significant benefits in terms of performance enhancement and injury prevention, it's crucial to use them judiciously and not become overly reliant on them. Understanding when and how to properly use a belt, along with selecting the right belt for your specific needs, can make a substantial difference in your lifting journey.

Remember, the goal is to complement your natural core strength and stability, not replace it. By making an informed choice, you can leverage the benefits of a weightlifting belt to safely push your limits and achieve your strength training goals.
