    The correct diameter

    Barbells come in two main diameter specifications: Standard (usually 25-30mm thick) and Olympic (50mm thick). It’s important to make sure you select the correct collar for your bar.

    Standard bars are generally the most common as they suit everyday lifters. They come in a variety of styles such a straight bars, curl bars and tricep bars for different types of exercises and movements, so no matter what type of weight training you do, there is a bar for you. Generally, collars are interchangeable between the different bars.

    Olympic barbells are thicker and stronger than their standard counterparts and can therefore hold much higher weight loads. For this reason, they are usually better suited to more experienced and competitive lifters. They have a thicker shaft diameter with a 50mm rotating sleeve on the ends. Due to their larger and heavier nature, Olympic bars are more expensive than standard bars. Generally, collars are interchangeable between the different bars.

    Bars come in a variety of lengths, styles and weight ratings – including straight barbells in 5ft, 6ft and 7ft lengths, EZ (or zigzag) curl bars, tricep (or hammer curl) bars, trap (hex) bars, dumbbells, fat bars, safety squat bars and more.

    All bars from little bloke fitness are supplied with collars.
