Adjustable kettlebells are strength training tools that people can use during their home workout. They allow people to add or remove weights to reach their fitness goals without taking up much indoor space.

This article discusses what to look for in adjustable kettlebells, along with their potential health benefits. It will also list some pros and cons and some adjustable kettlebells to consider purchasing.

Kettlebells are a type of home workout equipment that people may use for strength training exercises. They are dome-shaped and typically have a handle attached to the top.


Standard kettlebells have a fixed weight and come in varying sizes, while an adjustable kettlebell comes as one piece that a person can add or remove weight from as desired. Some kettlebells come with a leakproof bag, so an individual may add water, sand, or gravel to adjust their kettlebell’s weight.

Adjustable kettlebells are generally more cost-effective than buying sets of kettlebells and may suit individuals who have limited workout space.


Individuals can perform the same exercises with standard and adjustable kettlebells. Some of these include:

  • kettlebell swings
  • goblet squats
  • sumo upright rows
  • Russian twists

Individuals may wish to consider the following kettlebell features before making a purchase:

  • Handle: Kettlebells with a wide handle may suit taller individuals or those with larger hands. They may also suit people who wish to perform exercises involving holding a kettlebell with both hands.
  • Size: Adjustable kettlebells, especially those that require sand or water for adding weight, are larger than traditional variants. A person may prefer more space-saving exercise products.
  • Weight: Beginners may buy kettlebells that come with weights ranging between 5 and 10 pounds (lb). Those who exercise regularly may prefer a kettlebell with 30–40 lb of weight.

There are many adjustable kettlebells available for purchase. Below are some options that are suitable for people to use at home.

People who want to start exercising with adjustable kettlebells need to consider the following safety tips:

  • Starting slowly: Individuals who do not exercise regularly may wish to start with very light weights and increase them gradually. This may prevent muscle strain, pain, and soreness.
  • Breathing normally: People should breathe normally during strength training exercises, which may prevent hernias.
  • Stopping if they have sudden pain: Individuals who feel sudden or sharp pain during their workout should stop immediately and seek medical advice from a trusted healthcare professional.
  • Consulting a fitness trainer: Those interested in getting started with kettlebell training may consult a fitness trainer on weights and techniques.

The World Health Organization (WHO) says that people who do not partake in regular exercise may have a 20–30% increased risk of mortality than those who exercise regularly. They state that a person should perform at least 50–300 minutes of moderate aerobic exercise or 75–150 minutes of vigorous aerobic activity every week.

The Centers for Disease Control and Prevention (CDC) adds that people should perform muscle-strengthening activities twice a week. They also state that using equipment, such as adjustable kettlebells, for performing resistance exercises can improve a person’s overall muscle mass and function.

BreastCancer.org claims strength exercises may have the following benefits:

  • strengthening the bones
  • improving balance and posture
  • fixing muscle imbalance or weakness after breast cancer surgery

Additionally, a recent study found that over 80% of adults do not engage in muscle-strengthening activities. According to the researchers, these exercises may help prevent sarcopenia, a health condition that causes a decline in muscle mass or function.

According to BreastCancer.org, there are several adjustable kettlebell alternatives for muscle-strengthening exercises. These include:

  • weight lifting
  • exercises using resistance bands
  • bodyweight exercises such as pullups and pushups

Adjustable kettlebells may be the best option for people who wish to work out at home and have limited space. Strength exercises can improve muscle flexibility, prevent specific health conditions, and help strengthen bones.

Before making a purchase, a person may wish to explore different manufacturers and choose a kettlebell that best suits their needs.

However, individuals should speak with a doctor before practicing muscle-strengthening exercises if they have an underlying health condition.
