Frequently Asked Questions
Do CrossFitters need a weightlifting belt?
Not for every workout. Use a belt when attempting near-maximal lifts, heavy ladders, or when you need consistent abdominal bracing. For technique work, lightweight metcons, or mobility-focused sessions, train belt-free to build core resilience.
How should I size my belt for CrossFit?
Measure around your lower back at belly-button level (not pants size). Use the brand’s size chart and, if between sizes, choose the larger size so you can tighten appropriately. RDX specifically warns that pant sizes can mislead — follow lower-back measurements.
Are leather belts OK for Olympic lifts and high-rep sets?
Yes, if the profile is moderate (4–7mm) and the belt is broken in. Leather offers stable bracing, but very stiff or thick power belts can hinder hip drive and speed. Look for tapered or padded options if you do lots of cleans and snatches.
