Weight, handle shape, and overall design as some factors to consider before making a purchase.


According to one 2017 article, smaller kettlebells with rounded handles may be better for people with smaller builds.

Anyone doing exercises that involve holding a kettlebell with two hands — such as the swing, deadlift, or press — might need a kettlebell with an extra wide handle.


Kettlebells come in a variety of weights, of up to 100 lb. Using equipment that is too heavy can lead to injury, while using equipment that is too light may lead to insufficient results.

Generally, a kettlebell should be of a weight that allows a person to do about 10–12 repetitions in a set.

However, some exercise programs involve lifting very heavy weights with fewer repetitions. Overall, the right weight depends on a person’s goals and routine.


Some kettlebells have adjustable weights. These often have small, stacking plates that a person can add or remove.

Although the up-front cost may be higher, opting for an adjustable kettlebell may prevent the need to buy heavier ones over time.

Other kettlebells are shaped or color coded by weight. These variations do not usually limit effectiveness.

Using equipment correctly reduces the risk of injuries, such as sprains or strains.

When using a kettlebell, make sure the feet are planted firmly, with the body’s weight on the heels. When lifting a kettlebell, make sure the back is straight, and lift with the legs.

Never lift a kettlebell directly over the head, as dropping the equipment can cause significant injury.

Below are some common exercises that involve kettlebells.


People can do a few different types of squat using kettlebells. For example, a goblet squat involves holding the base of the kettlebell with both hands at chest height.

To perform a goblet squat:

  1. Stand with the feet shoulder-width apart. Bend at the hips and knees while pushing the hips back.
  2. Try to keep the chest up, the back straight, and the elbows forward while lowering into the squat position.
  3. Keeping the weight on the heels, drive the hips forward and return to the standing position.
  4. Repeat this 10–12 times per set.


This exercise can strengthen the legs, hips, buttocks, core, and back.

To perform a deadlift:

  1. Stand with the feet shoulder-width apart, holding the kettlebell with both hands in front of the body. Keep the arms straight.
  2. Bend at the knees to lower the kettlebell toward the ground, between the legs.
  3. Stop when the buttocks align with the knees, then return to standing.
  4. Repeat this 10–12 times per set.


This requires a person to maintain close control of the weight, which can increase the cardiovascular demands of the exercise.

To perform a swing exercise:

  1. Place the kettlebell on the ground, within arm’s reach.
  2. Squat, pick up the kettlebell, and swing it back between the legs.
  3. Once the kettlebell starts to swing forward, extend the hips and knees. With the arms extended, allow the kettlebell to rise to chest height.
  4. Lower the kettlebell and squat down again, allowing the weight to swing between the legs.
  5. Repeat this 10–12 times per set.


A clean and press exercise focuses on the shoulders, arms, and upper back. “Clean” is another word for “swing.”

To perform it:

  1. Stand with the feet hip-width apart. Grip the kettlebell in one hand.
  2. Do a movement similar to the swing, but as the kettlebell is in front of the body, in a smooth motion, quickly pull it to the chest, drop the elbow toward the rib cage, and rest the kettlebell on the shoulder of the hand holding the kettlebell.
  3. From this position, push the kettlebell up toward the ceiling while straightening the arm. Return the kettlebell to the shoulder, then let it drop down back into the swing position.
  4. Continue into the next rep or place the kettlebell on the ground and begin from a stationary position.
  5. Aim to repeat this for roughly 10–12 reps.

A slightly different version is the military press. This involves not doing the swing motion, but instead performing the shoulder press movement with a kettlebell in each hand.

Various types of equipment can help strengthen the muscles against resistance, including:

  • free weights
  • exercise machines
  • resistance bands

The choice may involve preferences, exercise type, cost, and available space for storage and use. A person may prefer kettlebells or free weights to exercise machines or circuit training.

Below are answers to some common questions about kettlebells.

Are kettlebells effective, and can I get a full body workout?

Kettlebells, like any type of fitness equipment, are effective if a person uses them correctly.

Kettlebells can enhance strength, improve cardio fitness, and improve endurance. People can use this equipment in a variety of exercises, such as squats, deadlifts, and presses.

Exercising regularly, such as three or four times a week, with weights may help a person see results sooner. However, a healthcare professional can provide individual guidance.

How heavy should my kettlebell be?

A person should choose a kettlebell weight that is comfortable for them to use.

If a person is just starting to use this equipment, they may wish to purchase a kettlebell that has a lower weight to reduce the risk of injury.

People who find lower weights are not giving them the workout they require may wish to increase the weight of their kettlebell.

Can I use kettlebells for cardio and weight training?

A 2019 article suggests that kettlebells can improve a person’s cardio fitness.

When a person exercises, their heart-rate increases, which leads to better cardiovascular health. Using kettlebells in exercises that increase heart-rate, such as deadlifts and swings, can supplement a person’s cardio training.

Kettlebells may provide an easy and versatile at-home training option, as people can use them to perform both cardio and strength exercises.

People should choose kettlebells that best fit their goals, space, and budget.

Also, people should always maintain good form when performing any exercise. This helps maximize results and prevent injury.
