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. The organization also states 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) add 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.

Additionally, 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 2020 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 health experts, there are several adjustable kettlebell alternatives for muscle-strengthening exercises. These include:

  • weightlifting
  • exercises using resistance bands
  • bodyweight exercises such as pullups and pushups

Here we answer some common questions about these products.

Are adjustable kettlebells worth it?

Adjustable kettlebells can be worth the price for persons who wish to exercise but do not have enough space for different weights.

People can choose kettlebells that they can adjust by adding sand or water. They can also opt for others that require replacing discs.

Is a 15 lb kettlebell too light?

The kettlebell weight depends on a person’s strength level and fitness experience.

People who are newer to exercise or do not have as much strength may find a 15 lb kettlebell offers enough resistance.

Are adjustable kettlebells safe?

Adjustable kettlebells can be safe so long as a person uses them appropriately. However, general tips on safety include warming up before exercising, stopping if the exercise causes pain, and letting the muscles rest between sessions.

How heavy of a kettlebell should I get?

People should choose a kettlebell that has a weight that allows them to exercise without injury. People may wish to consider getting a lower-weight product and gradually increasing it until they find the right weight for their needs.

Fitness professionals, such as personal trainers, can also offer advice on which product may be most suitable.

Adjustable kettlebells may be the best option for people who wish to work out at home with limited space. Additionally, strength exercises can improve muscle flexibility, reduce the chance of 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, people should speak with a doctor before practicing muscle-strengthening exercises if they have an underlying health condition.
