What are adjustable dumbbells?

Adjustable dumbbells are changeable weights that allow you to change resistance levels by adding or removing weight plates or using a dial mechanism. Instead of a massive rack taking over the room, you’ve got a whole range of weights tucked into one sleek pair, letting you switch from lateral raises to heavy presses with just a quick twist of a dial.

Can I drop these adjustable dumbbells after a heavy set?

No, we do not recommend dropping these dumbbells. Our adjustable dumbbells are designed with precise internal dialling gears, interlocking safety plates and a selector pin, so dropping them heavily on the floor or from overhead can misalign the mechanism and crack the internal components. After each training, return them to the storage tray and store them on a specific adjustable dumbbell stand or on the top layer of your multi-purpose weight rack. If you need dropping weights, choose bumper weight plates or cast iron weights.

How do the adjustable dumbbells 40kg work?

To change your weight, simply place the 40kg adjustable dumbbell into the custom storage trays, turn the dial on each end to your desired weight, and then grip the handle. Take it out and start your training. With each change of weight setting, it automatically secures the exact plate combination you selected while leaving the remaining plates in the tray.

Are 40kg adjustable dumbbells good for beginners?

Our 40kg adjustable dumbbell is also suitable for fitness beginners. However, due to its larger size compared to the 24kg adjustable dumbbell, it is better for intermediate and advanced lifters. If you want an adjustable dumbbell ready for your advanced training, you can use the lighter weights (5kg or 7kg) as a beginner. Move to the heavier weights once you are comfortable. We also have a 24kg adjustable dumbbell that is perfect for beginners.

What exercises can you do with adjustable dumbbells?

Adjustable dumbbells are built to withstand even the most intense workouts. You can hit everything from heavy chest presses and rows to deep squats, lunges, and deadlifts, building that rock-solid core and the kind of functional strength that shows up when it matters.

What are the weight increments on a 40kg adjustable dumbbell?

Our 40kg adjustable dumbbells allow you to smoothly scale your resistance from a light 5kg up to a heavy 40kg dumbbell. Our adjustable dumbbells contain 15 dumbbells in a set that you can quickly change in increments of 2kg to 3kg jumps. This is perfect for your progressive overload on both smaller isolation movements and heavy compound lifts.

Which is better: dumbbell set or adjustable dumbbells?

Fixed dumbbells (hex dumbbell sets) let you switch instantly, great for supersets or drop sets. But adjustable dumbbells take only a few seconds to change weight with a quick twist. Adjustable dumbbells are also cheaper long-term since one set replaces many weights. And if you are building a gym in a spare room, adjustable dumbbells are the absolute best for saving space while still giving you the range to earn every single gain.

Can you build muscles with adjustable dumbbell weights?

Adjustable dumbbells are capable of building muscle with proper routines. It’s all about that progressive overload; as you get stronger, you just click up the weight and keep the hard work going. Always challenge yourself and make sure those gains are being earned every single session. To maximise muscle growth, train each muscle group 2–3 times per week, use a rep range of 6–12 reps for most sets and perform 3–5 sets per exercise.

How do I store the adjustable dumbbells?

Keep the adjustable dumbbells on a flat, solid surface so they’re always ready for the next routine or buy a adjustable dumbbell stand with angled design for easier access during workouts.
