Lifting belts: size chart, lever vs prong and how to wear one

A lifting belt is the most misunderstood item in any gym. Most people believe it supports the back. It does not — and understanding what it actually does is what tells you when to wear one and how tight to make it.

Lifting belt size chart

Belts are sized by your waist at the navel, not by your trouser size. Every lifting and support belt we sell comes in S, M, L and XL:

How to measure

• Wrap a soft tape around your belly at the level of your belly button, where the belt will sit.
• Measure over the T-shirt you train in, standing relaxed. Do not suck in and do not brace.
• Do not go by your jeans size. A belt sits higher than trousers, so the number is usually 5 to 8 cm bigger.

On the line between two sizes? A prong belt has a row of holes, so either size will usually close. A lever is set to one position, so go by the waist you train at now, or come in and try one on. Every sport's sizes are on our size guides page.

A belt gives you something to push against

When you brace for a heavy lift, you take a breath into your stomach and tighten your abdominal wall. That raises the pressure inside your torso and turns your midsection into a rigid column your spine can work against.

A belt gives that expanding abdominal wall something solid to push into. The pressure rises further, the column gets stiffer. The belt is not holding anything up — it is giving your own muscles a surface to work against.

Which explains everything else about belts. It earns its place on heavy squats and deadlifts, where bracing is the limiting factor. It does nothing useful on curls, or on anything light enough that you were never really bracing.

Stiffness matters more than width

A belt that folds when you brace into it is not doing the job, whatever it measures across. Thick, stiff leather that holds its shape is what you are paying for.

Width is mostly about comfort and how you are built. A very wide belt can dig into the ribs of a shorter lifter in the bottom of a squat. Try it in the position you will actually use it.

Thickness, width and competition rules

Powerlifting-style leather belts are usually about 10 cm (4 inches) wide and 10 mm or 13 mm thick. A 13 mm belt is the stiffest and takes longest to break in, often a couple of months. A 10 mm belt is more forgiving and shapes to you within a few weeks, which makes it the easier choice for general training. Many gym belts, including several of ours, are wide at the back and taper towards the buckle so they do not dig in when you fold at the hip.

If you plan to compete, powerlifting federations cap the belt at 10 cm wide and 13 mm thick. Check your federation's current rulebook before a meet.

Lever or prong

A lever belt closes at exactly the same tension every single rep, and opens with a flick between sets. If you squat heavy and want the same brace every time without thinking about it, that consistency is the whole argument.

The trade is that changing the tension means unscrewing and repositioning the lever. Most people set it once for one lift and leave it.

A prong belt lets you change tension between lifts — looser for deadlifts, where a very tight belt can get in the way of the start position, and tighter for squats. It costs a few seconds between sets. If you want one belt for both lifts, this is usually the answer.

Neither is better. They suit different lifters and different training.

How tight

Tight enough to push against, loose enough to take a full breath into your stomach. If you cannot get air into your belly, you cannot brace, and you have made the belt worse than useless.

A rough test: fasten it, then take the breath you would take before a heavy squat. If that breath is impossible, go one notch looser.

When to wear it, and breaking it in

Put the belt on for your heaviest sets of squats and deadlifts, and for the last warm-up sets leading into them. Take it off for everything else: wearing it for every set means you never practise bracing on your own.

A new leather belt feels stiff and can dig in for the first few weeks. That is normal. Keep wearing it for your heavy sets, roll it up tightly in both directions when you are not using it, and it will shape to you. Nylon and neoprene belts need no breaking in.

Do beginners need one?

No, and there is an argument for waiting. Learning to brace without a belt builds the thing the belt later amplifies. Add one when the loads get heavy enough that your brace, not your legs or back, is what gives out first.
