GymKing 40kg Adjustable Dumbbells

GymKing 40kg Adjustable Dumbbells with Stand

Twenty weights per hand in the space of a shoebox. Try them in Buderim, or we'll ship them anywhere in Australia.

The GymKing 40kg Adjustable Dumbbell with Rack is a pair of twist-handle adjustable dumbbells that run from 2kg to 40kg in 2kg steps, each sitting in its own storage base, with a floor stand included. That's 20 weights per hand with no rack of fixed dumbbells to house, so it suits garage gyms, spare rooms and apartments where a full rack won't fit. Aussie Fitness Equipment sells them from our Buderim showroom on the Sunshine Coast and ships them Australia-wide.

Who is the GymKing 40kg for, and is it more than you need?

One pair of GymKing 40kg Adjustable Dumbbells replaces 20 pairs of fixed dumbbells, with weights from 2kg to 40kg in 2kg increments. Instead of storing 40 individual dumbbells on a traditional dumbbell rack, each GymKing adjustable dumbbell takes up just 447mm x 192mm in its adjustment base. A floor stand is also included, giving you a complete, space-saving dumbbell setup without the need for a full-size dumbbell rack.

The 40kg adjustable dumbbells are the heaviest option in the GymKing range, making them ideal for experienced lifters or anyone wanting plenty of room to progress. The higher weight capacity is particularly useful for heavier exercises such as dumbbell bench press, shoulder press, bent-over rows, goblet squats and Romanian deadlifts.

If you don’t need the full 40kg capacity, the GymKing 32kg Adjustable Dumbbells offer the same 2kg weight increments with a lower maximum weight. For lighter training or a more compact option, the GymKing 24kg Adjustable Dumbbells may be all you need.

How to use and look after adjustable dumbbells

Always change weight with the dumbbell sitting in its base. Twist the handle to the number you want, check both ends read the same, then lift straight up. The change takes a couple of seconds, so you can go from 36kg rows to 10kg lateral raises without walking to a rack.

Don't drop them. A fixed dumbbell shrugs off a fall onto rubber flooring; an adjustable one has a selector mechanism, and a drop can bend a plate or jam it. Wipe the handles after training, keep chalk and dust out of the base, and check the plates sit flat every few weeks.

Frequently Asked Questions

Is the GymKing 40kg Adjustable Dumbbell sold as a single or a pair?

A pair. The listed price covers two 40kg adjustable dumbbells and two storage bases, plus the plates and fittings. Each dumbbell adjusts independently, so you can hold a 40kg in one hand and a 10kg in the other for offset work.

What makes GymKing Adjustable Dumbbells different from other adjustable dumbbells?

GymKing Adjustable Dumbbells feature an all-metal construction with zero plastic in the dumbbell itself. This creates a stronger, more durable design built to handle regular strength training, while delivering a solid feel similar to traditional fixed dumbbells.

What weight increments do you get?

2kg steps from 2kg to 40kg, which is 20 settings per dumbbell: 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 36, 38 and 40kg. For most home lifters, that spacing is fine. If you want 1kg jumps for shoulder work, ask us about fractional plates for a barbell instead.

How quickly can I change the weight?

The fast twist adjustment system allows you to change weights in just seconds, making supersets, drop sets and circuit training quick and efficient.

Can I drop adjustable dumbbells?

No, and that goes for every brand of selector dumbbell, not only GymKing. The mechanism relies on plates seating precisely, and a drop can bend a plate or jam the selector. Drop damage isn't a manufacturing defect, so the 3-year warranty doesn't cover it.

Is the rack included, and is it a floor stand?

Two storage bases are included, one per dumbbell, and that's what 'rack' means for this product. They're low bases measuring 447mm x 192mm x 195mm with the dumbbell in place, made to sit on the floor or a bench. There's no separate tower stand in the box.

Do you ship the GymKing adjustable dumbbells Australia-wide?

Yes. We ship every weekday from Buderim on the Sunshine Coast to every state and territory. Add the pair to your cart and enter your postcode for the freight price. In-stock orders dispatch within 48 hours.
