What are Adjustable Kettlebells?

As the name implies, an adjustable kettlebell is a kettlebell that allows a user to adjust the weights used during a workout. It is a multi-piece item that consists of a handle and various weights that are added or removed as needed. Following is a comprehensive overview of how these kettlebells work, when they should be used, and what to look for when buying one.

What are the Benefits?

The most obvious benefit of buying an adjustable kettlebell is that you won’t have to invest in a whole set of different kettlebell weights every time you want to change the amount of weight you lift. Furthermore, an adjustable kettlebell does not take up nearly as much room as a full kettlebell set, making it an ideal option for those who have limited storage space.

How to Best Use Adjustable Kettlebells

Adjustable kettlebells can be used in the same way as regular ones. However, they can be a little more challenging to handle at first. It is not uncommon to find that these kettlebells don’t swing as naturally as fixed ones. In many cases, the problem lies with buying a poorly made product; however, even those who purchase a top quality one will need to get used to using such a kettlebell before they feel entirely comfortable with it.

Once you have purchased and adjusted your kettlebell to suit your needs, start with basic moves such as lateral lunges, bicep curls and kettlebell swings. Once you get the feel of working out with your new kettlebell, progress to challenging exercises such as the halo and swings with deep squats.

Who Should Buy One?

Adjustable kettlebells are best for those who have some experience working out with a kettlebell and are committing to doing kettlebell exercises long-term. Investing in an adjustable kettlebell is a great idea if you have discovered the many benefits of using a kettlebell as part of your workout routine and intend to use this device on a regular basis.

What to Look for When Shopping for an Adjustable Kettlebell

Pay close attention to the handle as it is the most important part. A good handle should be suitable for kettlebell workouts with one or both hands. It should feel sturdy and should not have a seam that would cause discomfort during a workout session. A handle made from either from enamel or with a powder coat finish is best as such a handle won’t slip in your hands while you are working out.

It is also important to check the handle weight. Some brands offer handles that weight as little as 5 lbs. while other companies sell adjustable kettlebell handles that may weight up to lbs.

The quantity and weight of the plates to be added to the kettlebell should also be taken into consideration. A single plate may weigh anywhere from 3 to 5 lbs. This means that an adjustable kettlebell with all the weights added could weigh as little as 12 lbs. or as much as 40 lbs.

Finally, consider what shape of kettlebell you want to use. Many adjustable kettlebells are round, which means they are the same shape as a fixed weight kettlebell. However, some adjustable kettlebells use square weights. No one type is necessarily better than the other, but you will need to try both types out to see which shape you feel most comfortable with.
