The Verdict
  • Solid Steel Construction: This traditional looking kettlebell features a solid steel construction that is incredibly durable and sturdy and is built to last a lifetime.
  • Cylinder Weights: Instead of the traditional plates, the Rocketlok utilizes cylinder weights made from solid steel. You don't need any tools to remove the weight and the slide locking mechanism makes it very easy to adjust the weights.
  • Compact: The Rocketlok is a very compact piece of equipment that makes it very easy to store. At the height of 9 inches and width of 8 inches, it's a piece of cake to store these kettlebells in any closet when not in use.
  • 24-36lbs Weight Range: This Rocketlok adjustable kettlebell features a 23-36lb weight range, which is suitable for intermediate/advanced users or those moving up from Rocketlok's smaller weight unit. The kettlebell comes in four adjustments; 24lbs, 28lbs, 32lbs, 36lbs.


  • Solid Center of Gravity: The balance and center of gravity of the Rocketlok stay consistent at every weight, which is a huge benefit while performing your kettlebell training, so you'll see results and reach your goals quicker.
  • No Rattling Movement: Another great design feature is that there is no rattling or movement of the weight while you're using the kettlebell. This is great for people who find noisy kettlebells annoying.
  • Easy To Adjust Weights: The tool-less design and simple slide locking mechanism make it very easy to adjust the cylinder weights, so you'll be able to increase of decrease the weight very easily with little delay.


  • Low Weight Range: The only true disadvantage to the Rocketlok adjustable kettlebells is the relatively low weight range. With only four adjustment options, you'll have to size-up eventually, which may cost you more down the line. However, this kettlebell is very inexpensive, and if you were to purchase this and the lower weight range model, you'd have a great beginner set that would see you through the beginner, intermediate and advanced stages of your kettlebell training.
  • Wide Handle: It's a very small issue, but the handle of the Rocketlok adjustable kettlebell is pretty wide. This might make it difficult to hold for women or men with smaller hands. This is a minor issue, however, and it's unlikely to cause any major problems.

What You Get

You'll receive the Rocketlok adjustable kettlebell with four adjustment weight cylinders. You'll also receive a 1-year warranty with this product.

The Verdict
  • Traditional Design: Like the higher weight range model, the lower range Rocketlok features a traditional kettlebell design with a sturdy solid steel construction and a shape that helps maintain your center of gravity while in use.
  • Cylinder Weights: Instead of the traditional plate system of weights, the Rocketlok changes it up a bit by using cylinder weights instead.
  • Compact: Even smaller and more compact than the higher weight range model, the Rocketlok 14-20lb model is very compact, so it's easy to store in any closet or corner when not in use.
  • 14-20lb Weight Range: The 14-20lb weight range is a great option for beginners with 3 weight increments of 14, 17 and 20lbs.


  • Great For Beginners: This lower weight range Rocketlok is a fantastic option for beginners who want to get started with kettlebell training without having to jump straight into heavy weights right away. The 3 weight options also mean you can upgrade slowly as your strength increases.
  • Smooth Workout: The Rocketlok provides a very smooth workout thanks to the cylinder weights that don't rattle or move while in use. Also, due to the traditional shape of the Rocketlok, your center of gravity remains the same even when you adjust the weights, so you'll maintain your balance for a more consistent workout.
  • Easy To Use: Another great pro of the Rocketlok is how easy it is to use. You can adjust the cylinder weights very easily thanks to the tool-less design and slide locking mechanism.


  • Low Weight Range: As with the higher weight range Rocketlok, the only real downside to this model is the relatively low weight range. With only three weight increments (with the highest at 20lbs), you will have to upgrade to higher weight range model at some point. However, this is a fantastic model for beginners as it takes the pressure off to reach a very high weight soon after starting.
  • Not Suitable For Advanced Users: Of course, because this is great for beginners, it is equally less great for more advanced users. Considering the low weight range, advanced users would find little challenge with this kettlebell. However, advanced users can simply opt for the higher weight range model instead.

What You Get

You'll receive the Rocketlok adjustable kettlebell with three adjustment weight cylinders and a 1 year warranty.

Adjustable kettlebells offer a wide array of benefits for your health and fitness. We outlined some of the main ones below:

  • Adjustable: We’ll get this one out of the way first. The obvious advantage that adjustable kettlebells have over regular kettlebells is that you can adjust the weights. So you can continue to improve your strength without needing to constantly replace single kettlebells.
  • Build Strength: This may seem obvious, but adjustable kettlebells are fantastic for building strength. In fact, if you want to increase your strength, kettlebell training is one of the best workouts you can do. You can build strength in your arms, legs, back and abs and with adjustable kettlebells, you can keep adding weight as your strength improves.
  • Keeps Your Heart Healthy: Kettlebell training is a very effective cardio workout. As you work out with your adjustable kettlebells, you increase your heart and lung activity, which is great for cardiac health. Kettlebell training can have the same heart-healthy effects as running for several kilometers.
  • Lose Weight: Kettlebell training burns a lot of calories and is quickly becoming one of the most widely advertised exercises for weight loss. As you use your adjustable kettlebells, you not only burn calories but also build muscle and speed up your metabolism, which boosts your weight loss further.
  • Build Muscle: Again, this may seem obvious but adjustable kettlebells really are fantastic for developing lean muscle and building muscle mass. There are many different kettlebell exercises designed to target specific muscle groups, so you’ll be able to build muscles all over with this great full-body workout.
  • Increase Endurance: The more you train with kettlebells, the more your endurance will improve. Continued endurance training should increase your stamina with each session, which is why adjustable kettlebells are great. As you improve, you can continue adjusting the weight, so your training never becomes stagnant.
  • Improve Balance: Adjustable kettlebells are also great for training your balance. As you shift the weights, your center of gravity will be thrown, so it’s an excellent training for maintaining balance.
  • Improve Flexibility: Another great benefit of adjustable kettlebells is that they improve your flexibility. There are a huge number of kettlebell workouts that can’t be done with regular dumbbells that will help to improve your flexibility.
  • Workout At Home: Another obvious but wonderful benefit of adjustable kettlebells is that you can achieve a fantastic workout all from the comfort of your own home. Definitely useful in this cold weather when you’re unwilling to make it to the gym.
  • Affordable: One of the reasons adjustable kettlebells are so popular is that, as well as providing a great workout, they’re affordable, so they’re great for people wanting to build a home gym on a budget. Plus, adjustable kettlebells eliminate the option of having to replace your existing kettlebells when you want to up the weight. Forget $1000 gym membership and just buy adjustable kettlebells instead.

Factors To Consider Before Buying Adjustable Kettlebells

So, overall adjustable kettlebells sound pretty great, right? Right. So now that you want to get a set of your own, there are a few things to consider before buying.

  • Range of Weights: Even though adjustable kettlebells offer a great range of weight, it’s impossible to find one that will handle every weight available. Look for one in your required weight range. In general, women tend to start off with 22-26lbs and men with 26-30lbs.
  • Weight Increases: Also look at each of the weight increases available on the adjustable kettlebell and see if they suit your needs.
  • Size: It may seem obvious but is often overlooked. You’ll be using your adjustable kettlebell a lot so look for one that is the right size for you and that you can grip comfortably in your hands.
  • Material: The material used in the adjustable kettlebell is a sure sign of the quality. Cast iron or steel are always good options, while plastic should be avoided where possible.
  • Warranty: Does the adjustable kettlebell have a warranty? What does it cover? Check to see if your adjustable kettlebell comes with a warranty for an extra piece of mind.
  • Price: And of course, you should factor in the cost of your adjustable kettlebell and how much you’re willing to spend.

Tips On How To Choose Adjustable Kettlebells To Suit Your Needs

Finally, before we get into looking at some adjustable kettlebells in detail, there are a few more tips for choosing the right adjustable kettlebell to suit your needs.

  • Quality is important with adjustable kettlebells. In some lower quality models, the kettlebell can be flimsy and even unsafe. Always make sure you purchase a quality kettlebell, so you don’t do yourself any damage.
  • Adjustable kettlebells can be noisy due to the weights shifting during use. This doesn’t happen with all models so if it’s something that would bother you, then look for models that aren’t noisy.
  • There are a few different options in the adjustable kettlebell department. Aside from the traditional plate method used by most adjustable kettlebells, you can also find models where the kettlebell is made up of an empty body that can be filled to add weight.
  • Some adjustable kettlebells come with a training DVD. If you feel like you would benefit from a DVD to show you some of the training exercises, look for adjustable kettlebells that come with one.
  • If you have back or shoulder problems, unfortunately, adjustable kettlebells may not be for you. If this is the case, you should only use a kettlebell, fixed or adjustable, in the presence of an instructor.
