The best kettlebells for your home gym, from 4kg to 10kg

There are several reasons why you might want to add a couple of kettlebells to your at-home workout stash. Not only are they incredibly versatile (they can be used for a whole host of different exercises that target multiple muscle groups) – and great for helping to improve strength, endurance and explosive power – but kettlebells are also super convenient to store away out of sight thanks to their compact size.

Similar to a dumbbell, the humble kettlebell is a type of weight found in most gyms and used in the majority of strength training and resistance training classes. They're normally made from cast iron or cast steel, can be vinyl coated, and are shaped into round balls with handles on the top for easy grip.

Kettlebells come in various different sizes and weights – ranging from 4 kg to 48 kg (or more). And they can be used for a whole range of compound moves – squats, lunges, push-ups and glute bridges, to name a few – kettlebell exercises can be added to any workout to really spice things up, and will help you build the all-important core strength so essential for daily life. Consider your home workout elevated.

In short, loads. Studies have found strength training – surprise, surprise – can improve muscle strength, muscle gain, blood pressure levels, bone mineral density, blood glucose levels, and more.

Strength training is a great way to build muscle and tone up, and has also been found to boost your body's state of EPOC – that's excess post-exercise energy consumption. That basically means, while you may not burn loads of calories while working out, your body will continue to for hours post-sweat session. Not bad.

But kettlebells aren’t just for building strength, oh no. Kettlebell exercises can also get your heart rate up and challenge your cardiovascular system. And, they can even help to improve your flexibility and mobility since most kettlebell exercises tend to involve dynamic movements that require a range of motion in your joints.

For complete beginners, a kettlebell weight in the range of 4-12 kg is a good starting point for women, while men may want to start with a slightly heavier weight, around 12-16 kg.

Of course, these are just general recommendations and should be adjusted based on your current fitness level and strength. It's also important to think about the specific exercises you'll be using the kettlebell for, as some exercises – such as renegade rows (which combines a press up, row and plank) – may require a lighter weight, while others – for example, a goblet squat – may require a heavier weight.

We recommend choosing a weight that feels challenging but still allows you to maintain proper form and technique. After all, it's much better to start with a lighter weight and focus on learning and maintaining proper form and technique before increasing the weight.
