## Long description

Short straight exercise bar from Marbo Sport, model Kub\_05-CBR35K/30, designed for strength training with a 30 mm sleeve diameter. This compact bar is intended for targeted upper-body work such as biceps curls and triceps extensions, and is compatible with standard 30 mm Olympic-style plates. The screw collar (bolt-type) clamps provide a simple, secure way to fix weight plates for home or small gym setups where space is limited.

Key specifications
 Bar type: short straight exercise bar
 Sleeve diameter: 30 mm
 Clamping system: screw collar (bolt-type) clamps
 Compatibility: standard 30 mm Olympic-style weight plates
 Typical uses: isolation and accessory upper-body exercises
How to use
Load compatible 30 mm weight plates onto each sleeve, making sure plates are seated flat against the inner collar. Thread the screw collar clamps onto the sleeves and tighten securely to prevent plate movement during exercise. Use the bar for controlled repetitions in curls, triceps extensions, and other close-grip movements; maintain correct technique and a stable stance to reduce risk of injury. Inspect collars and sleeves periodically for secure fit before each session.
Usage recommendations
For safe operation, check that the screw collars are fully tightened before each set and avoid dynamic drops or uncontrolled impacts on the sleeves. Pair the bar with plates that match the 30 mm sleeve diameter and distribute weight evenly on both sides. For longevity, keep the sleeves clean and dry and tighten clamps after storage or transport.
