Apex Kettlebell

The Apex adjustable kettlebell has a classical cast-iron design that mimics the standard look. It includes a 15lb weighted handle, 5lb bottom plate, and four non-weighted spacer disks that can be removed and replaced with weighted options. These can be purchased separately or you can use standard 2.5lbs, 5lbs, or 10lbs weight plates.

We like its heavy-duty design and traditional u-bar handle which feels like using a standard kettlebell. It also receives consistently high 4* and 5* reviews from customers.

  • Pros – durable, u-bar handle mimics traditional kettlebell grip, simple screw-pin adjustment, consistently positive customer reviews.
  • Cons – additional weight plates aren’t included as standard.

⇒ Buy from Amazon US.

Kettle Gryp Adjustable Kettlebell

The Kettle Gryp is a genius product that turns any dumbbell into a kettlebell! It weighs less than 1lb which makes it super-portable, but can hold most standard dumbells up to 55lbs. Its striking yellow design and curved edges make it the most stylish option on this list.

It has a simple latch mechanism that allows you to insert almost any type of dumbbell. Once clicked shut, it functions just like a traditional kettlebell! An incredible 77% of this product’s 3700+ reviews are 5* so you can be confident that it’s a solid purchase.

  • Pros – low price, sleek design, simple adjustment, easy to transport.
  • Cons – requires dumbbells.

⇒ Buy from Amazon US or Amazon UK.

Ironmaster Adjustable Kettlebell

Ironmaster is renowned for manufacturing high-quality free weights and their dumbbells are particularly popular. The Ironmaster kettlebell is actually just a handle which you can attach dumbbell weight plates to. This makes it ideal for people who already own other Ironmaster accessories or PTs looking for a complete free-weight solution.

The handle alone weighs 22.5lbs which is much heavier than many of the other products on this list. It can be extended up to 80lbs which makes it a serious training tool and probably not one for beginners. The handle can be used with one or two hands and comes with a lifetime warranty so you can be confident in its durability!

  • Pros – heavier weight extension possibilities, highly durable, lifetime warranty.
  • Cons – more expensive than other kettlebell products, doesn’t include adjustable kettlebell weights, starting weight of 22.5lbs may not be suitable for beginners with less strength.

PowerBlock KettleBlock

The PowerBlock adjustable kettlebell features their clever switch technology that made their dumbbells so popular. It has colour-coded weight increments that range from 8-40lbs (in case you’re interested, these are 8, 12, 20, 25, 30, 35, 40).

The PowerBlock kettlebell effectively replaces eight separate kettlebells or 186lbs in weight which is a huge space-saver. You can also get a 20lbs option for slightly less but this gives less versatility for progression.

  • Pros – heavier weight extension possibilities, highly durable, lifetime warranty.
  • Cons – more expensive than other brands, starting weight of 22.5lbs may not be suitable for beginners with less strength.

Rocketlok Kettlebell

The Rocketlok adjustable kettlebell features a solid cast steel body and traditionally shaped handle. You can easily change the weighted interior cylinders to adjust the difficulty between 14, 17, and 20lbs.

It’s also designed in a way that maintains a consistent balance at every weight levels which aids correct form. It has the best adjustable kettlebell review percentages, with 84% of customers awarding it 5 stars.

  • Pros – traditional kettlebell shape and handle, simple adjustment.
  • Cons – limited to 3 weight increments, high price relative to the number of weight options.

⇒ Buy from Amazon US or Amazon UK.

Wildcard Option – Kettlebell Sandbag

An alternative option is to go for a kettlebell sandbag – it’s the cheapest solution and lighter to transport too. The downside is that the adjustments are less precise.

You’ll know how much it weighs when full but judging whether it’s half or two-thirds is trickier. This means that you might not always be training with the exact weight you think.

Buy it on Amazon US or Amazon UK.

How To Use Adjustable Kettlebells

In terms of exercises, both adjustable and standard kettlebells can be used in exactly the same ways. You can perform kettlebell swings, goblet squats, sumo upright rows, Russian twists, and any number of other movements using them.

However, making adjustments in order to change the weight is slightly different. With a standard kettlebell, you just pick up a different weight for whichever exercise you want to perform. For adjustable ones, you’ll need to loosen a latch or lock, then add or remove weights, and tighten everything back up so it’s 100% secure.
