Using these barbell collars is a breeze. Just slide them onto the ends of your 50mm Olympic barbell and tighten them up. Make sure they're snug so the weights don't slip during your workout. When you're done, simply loosen them and remove. To keep them in good shape, wipe them down after each use to prevent rust and dirt buildup. Store them in a dry place. Also, don't over - tighten the collars as it might damage the barbell or the collars themselves.
