Frequently Asked Questions

What is the RELENTLESS X Weightlifting Belt used for?

It gives you a firm surface to brace against during squats, deadlifts, cleans, snatches, overhead movements, and heavy training.

Is the RELENTLESS X approved for competition?

The 4-inch profile is commonly accepted in many events, but always check your specific competition or federation rules.

What makes a nylon belt different from a leather belt?

Nylon belts are more flexible, comfortable, and easier to adjust during dynamic workouts compared to stiff leather belts.

Can beginners use this belt?

Yes. It is suitable for beginners and advanced athletes who want better bracing, support, and lifting confidence.

Does wearing a belt make your core weaker?

No. A belt supports proper bracing. It does not replace core strength when used correctly.

When should I wear a lifting belt?

Use it during heavier sets, strength work, squats, deadlifts, Olympic lifts, and workouts where extra core support is helpful.

Can I use it for functional fitness workouts?

Yes. The quick-lock buckle makes it ideal for workouts that combine lifting, conditioning, and fast transitions.

How tight should my belt be?

It should feel secure but still allow you to breathe and brace your core properly.

What size should I choose?

Measure around your waist at your belly button, not your pants size. If between sizes, size up.

How does the quick-lock buckle work?

It allows fast tightening, loosening, and removal between sets or workout movements.

Will a belt make my core weaker?

No. A belt is a bracing tool. You still brace your own core against it, and it helps you hold a strong position under load.

How do I clean the RELENTLESS X Belt?

Hand wash with mild soap and water, then air dry completely. Do not machine wash or use harsh chemicals.

Relentless lifting belt FIRE

I love it so much!! I got the Pink Riot Relentless lifting belt. This belt is top notch material and durable. The area for the patch and the rubber parts of the belt are so cool. The locking mechanism is top tier.

Best multi purpose belt I’ve ever used

Best multi purpose belt I’ve ever used. Replacing the plastic locking bar with metal for a very nominal price increase is what really puts this one over the top. The plastic bar on all previous belts I’ve use is always the one weak point and what eventually gives out…..unfortunately both times right in the bottom of a deep heavy squat! That’s no longer an issue.
