Adjustable Dumbbell Bundle 100% Steel – HR-36P 4 to 36 kg + HRBD Adjustable Bar

Bundle contents

• 1 pair of 100% steel adjustable dumbbells, 4 to 36 kg, 1 kg increments (ref. HR-36P)
• 1 quick-change adjustable bar, 87 cm, 100% metal (ref. HRBD)
• Square plates shared between the dumbbells and the bar
• Expandable up to 65 kg per dumbbell with the extension kit (sold separately)

The 1 kg increment matters most on the bar

With two hands the load is distributed differently and progression follows a slower rhythm than unilateral work. On a barbell curl or a skull crusher, going from 24 to 26 kg is sometimes the jump too far, whereas a 1 kg increment lets you complete the set cleanly. The 500 g micro-plates of the HR-36P pair apply directly to the HRBD bar, which the 2 kg increment version does not allow.

This precision also counts on two-handed isolation movements, front raises and overhead extensions first among them, where working loads stay modest and a 2 kg gap represents a variation of 10 to 15%.

Unilateral and bilateral from the same stock of iron

Working with two dumbbells forces each side to manage its own load, which corrects imbalances and recruits the stabilisers. The bar gives a firmer anchor point and better force transfer on a given movement. Alternating the two formats across a cycle avoids the stagnation that comes with always training the same way.

The HRBD bar uses the square-plate system with safety pins and the thumbscrew clamping of the pair. Transferring the load takes a few seconds, with no tooling. At 87 cm and 11 kg unloaded, it requires neither a rack nor a stand. Note that as the plates are shared, the two tools are used alternately. The technical detail of the pair is on the 4 to 36 kg adjustable dumbbells page.
