Threebar

Threebar is a type of barbell that features three sections, each connected by a central pin. This design allows for a greater range of weight adjustments compared to traditional two-section barbells. The three sections are typically referred to as the lower section, the middle section, and the upper section. The lower section is usually the heaviest, while the upper section is the lightest. The middle section can be adjusted to add or remove weight, providing a wide range of lifting options.

The threebar design is popular among powerlifters and strongmen due to its versatility. It allows for a greater range of weight adjustments, making it easier to find the optimal weight for a given lift. Additionally, the threebar design can be used to create a "double barbell" configuration, where two threebars are connected together to create a single, heavier barbell. This configuration is often used for heavy squats and deadlifts.

However, the threebar design also has some drawbacks. The central pin can be a weak point, and it can sometimes break under heavy loads. Additionally, the threebar design can be more difficult to balance than a traditional two-section barbell, especially when using heavier weights.

Overall, the threebar is a versatile and powerful tool for strength training, but it requires careful handling and maintenance to ensure safety and longevity.
