Best adjustable dumbbells for home workouts

Strength training is a vital component of any triathlete’s training regime, helping with technique, performance and injury prevention, but too many of us neglect it.

That’s why many coaches recommend following a well-rounded strength and conditioning plan either at home or in the gym.

Alongside resistance bands other kettlebells, adjustable dumbbells are one of the best pieces of kit to help you do exactly that. This is our guide for what to look out for, plus some options you may want to consider.

Why buy an adjustable dumbbell?

One of the biggest advantage of gyms is the access you get to different weights, allowing you to progressively overload different movements and develop your strength by increasing how much you’re lifting.

But gyms can be expensive, busy and, if you don’t live nearby, it can take up a lot of time getting to them. That’s where adjustable dumbbells come in, as they allow you to work out at home, while still being able to increase the load you’re lifting.

Plus, rather than a clunky rack of expensive dumbbells, which take up space and mean you have to purchase a new pair every time you want to change weight, adjustable dumbbells fit a range of weights as a set of attachments.

While they may appear expensive at first, the upfront cost will likely save you money in the long run.

Types of adjustable dumbbells

There are a few different main types of adjustable dumbbells, varying based on the mechanism used.

  • dial: The dial mechanism is a contraption that allows you to spin a dial to select the specific weight. While the weight is racked, the correct number of plates will be selected for the necessary load.
  • Digital: Is even turning a dial a little old school? The most technologically-advanced dumbbells take adjusting weight to a whole new level. The plates will automatically attach to the bar at the touch of a button, saving you precious energy between sets.
  • Screw/Spin lock: The traditional style of these dumbbells is often a testament to their reliability and longevity. The task of loading up the plates and spinning on the screws can be arduous, but with a good pair can be versatile and good value for money.

Best adjustable dumbbells for home workouts

Bowflex SelectTech Adjustable Dumbbells

This popular set of dumbbells from Bowflex has a weight range of 2-24kg, allowing you to build up in increments to find the right weight for your chosen workout.

The dial system is said to switch between the plates dynamically, which the brand says makes transitions between exercises smooth and painless.

The plates are made of aluminum and come with their own stand. Something worth bearing in mind, however, is that the listed price is for one dumbbell, so if you want a pair you’ll need to order two.

Yaheetech 30KG/20KG Adjustable Dumbbells

This pair of spin lock dumbbells use sand and cement as an internal filler with a plastic exterior, along with a smart chrome-finish iron bar.

They’re available in an overall weight of 20kg or 30kg, or a max weight of 10kg or 15kg per dumbbell.

This weight is made up of plates that range from 2.5kg to 1.25kg, so they’ll take quite a lot of adjusting, but are able to accommodate for a wide range of strengths and abilities.

They also feature non-slip handles, which Yaheetech claims create enough friction to ensure you have enough grip throughout your workouts.

Opti vinyl barbell and dumbbell set

This weights set from Argos’ Opti line can facilitate a maximum weight of 35kg and come with dumbbells and a barbell for greater workout versatility.

Their plates are constructed with vinyl and concrete in an attempt to deliver a sturdy, high-quality experience, and feature a spinlock adjustment method.

Each dumbbell can hold a maximum weight of 17.5kg.

Powerblock Sport 2.4 Adjustable Dumbbells

These popular dumbbells have been praised by consumers for their stability and compactness, and use a dial system to replace eight different weights.

This pin lock is designed to make them compact and easy to store.
