Adjustable Kettlebell Review and Why You Should Get One

Why Do People Love Them?

Kettlebells offer a unique workout because they require you to use both your upper body and lower body at the same time. This makes them a great option for people who need to work out multiple muscle groups simultaneously.

The Benefits/Reasons to Use Kettlebells

Kettlebells offer several benefits for people who use them regularly. They help with cardiovascular conditioning, core strength, flexibility, and balance.

Kettlebell type weights have been found in many countries, from Scotland, Greece, and China, to Russia, and Germany. Recently in North America they have gained popularity as a great way to build strength and improve overall fitness.

A Bit of Kettlebell History

Kettlebells are little more than weights with handles on top.

Some suggest
that objects resembling kettlebells were used as far back as classical Greece.

Shaolin monks in China and Highland Game athletes in Scotland used them. Some called them “ring-handled weights” while others called them “stone padlocks.”

 Some purists would not call all of these weights “kettlebells”, but they do bear a resemblance.

The Limitations

However, there are some limitations to using kettlebells as well.

Are kettlebells worth the effort and expense? The best answer is, are you really willing to learn to use them with proper form? You should be willing to invest some time and money for coaching sessions or other learning resources to learn the workout, otherwise they are not the right exercise equipment for you.

There is no one-size-fits-all kettlebell for everyone, and it depends on your strength, skill, and the exercise you want to do – to determine what weight you will want to use. That is the beauty of using an adjustable kettlebell. You can choose one kettlebell that adjusts from 8 to 40 lbs instead of purchasing 6 different kettlebells.

Adjustable Kettlebell Reviews – What to Look for In a Kettlebell

An adjustable kettlebell has a locking mechanism that allows you to easily adjust the weight by adding or removing plates. Often the adjustments are in increments of 5 pounds with an overall weight from 10 to 40 lbs.

When looking for a kettlebell, choose one with a comfortable grip so you do not worry that it could slip from your hands. It should also be wide enough, depending whether you are using it with one hand or two.

  • Can you quickly and easily adjust the weights?
  • How long is the warranty?
  • Does it have a plastic or metal locking system?
  • Does the kettlebell change shape as you add or remove weights?

Find a weight that you can press overhead eight to 10 times with good technique yet still find challenging.
