What makes a adjustable kettlebell different from a traditional kettlebell?

The main difference that sets apart an adjustable kettlebell from a traditional kettlebell is its adaptability. While standard kettlebells come in fixed weights, adjustable kettlebells offer a range of weight options in one single package.

Typically, an adjustable kettlebell has a mechanism that allows you to add or remove weight plates, which gives you the flexibility of customising the weight to suit your own fitness level and workout requirements. This ease and versatility makes adjustable kettlebells a great choice for individuals of all fitness levels, from beginners to advanced athletes.

Also, the best adjustable kettlebells are space-saving, often cost-effective and convenient, making them a popular choice for home gyms and individuals looking to diversify their workouts without cluttering their home with lots of different kettlebells of varying weights. They are a great piece of equipment that can complement your dumbbell or resistance band workouts.

So, say goodbye to your cluttered living area doubling as a kettlebell station, and hello to customisable and space-saving strength training. You're in the right place to discover the best adjustable kettlebells that will take your fitness routine to the next level.

Are adjustable kettlebells any good?

Simple answer - we wouldn't be writing about them if they weren't any good.

Adjustable kettlebells can be an excellent fitness tool for those looking to optimise their workouts and save space in their living area. These versatile weights allow you to easily change the resistance level, sometimes with just the click of a dial, making them suitable for beginners and experienced enthusiasts alike. Also, their adaptability means you can target different muscle groups and adjust the intensity of your exercises, helping with both strength and endurance gains.

If that isn't enough, adjustable kettlebells are cost-effective as they eliminate the need to purchase multiple fixed-weight kettlebells or dumbbells.

Is a 10kg kettlebell too heavy?

Whether a 10kg kettlebell is too heavy for you depends on your own fitness goals and current level. For some, a 10kg kettlebell may be more than enough to hold during exercises like swings, squats and lunges. It provides plenty of resistance to challenge your muscles and promote gains, especially for individuals who are new to kettlebells. However, as a beginner we'd advise to start with a lighter kettlebell to learn the movements correctly, then think about gradually increasing the weight as you get stronger.

Alternatively, experienced lifters may find a 10kg kettlebell too light for certain exercises and may choose heavier weights to continue their progress. Our 'best' list is comprised of options for both beginners and advanced lifters.

Should I do more reps or use heavier kettlebells?

If your aim is to build muscular strength and power, opting for heavier kettlebells with lower reps (typically 6-8 repetitions per set) may be more effective. Heavier weights will help to stimulate muscle growth and strength gains. However, if you're trying to enhance muscular endurance and cardiovascular fitness, using lighter kettlebells with higher repetitions (something along the lines of 10-15 more per set) can be more beneficial. An ideal approach is one with variety to avoid plateaus and ensure continuous progress. So both approaches could be incorporated into your routine for a well-rounded fitness level.
