Anatomy of kettlebell

Firstly, let check how kettlebell is structured?

A kettlebell includes:

  • Bell: the part deciding main weight of the kettlebell
  • Handle: is the gripping part that attached with the bell part by horn. From horn up and to the corner, bend the angle to form an arc.

Regarding some of competition kettlebells, there are hollow core at the bottom that is connected to the empty core inside the bell.

Hollow core of kettlebell

Today, kettlebell is divided into 2 main types called competition kettlebell and classic kettlebell. Let’s analyze their characteristics with us!

Competition kettlebells (also known as pro grade kettlebells or sport kettlebells)

Competition kettlebell is used in competitions or for those who want to practice professionally. The reason is that the competition kettlebell has the handle design and the bell size that does not change even though the weight does.

Even if you hold a competition kettlebell 10kg or 40kg, their sizes are still the same. The handle parts are also the same from size to distance.

The shape of the competition kettlebell’s handle is rectangular; perpendicular edges. The sides are upright and bent at the 2 corners.

Some competition kettlebell manufacturers will keep the original hollow core at the base. This does not affect the quality of the base.

With such a hole, when the manufacturer wants to change the weight of the kettlebell, they just need to add metal to the bell quite conveniently. This also allows the kettlebell’s weight to be pushed towards the handle for increased balance and stability, making it easier for the practitioner to rotate the wrist.

The cast iron kettlebell is cast with solid bowels, so the bell size and handle width vary by weight.

The larger the weight, the larger the bell diameter and the larger the handle width.

The handle shape of the cast iron kettlebell is an arc, which is bent from the horn to the corner and gradually widens to the sides. The material of classic kettlebells is usually cast iron, and because of the monolithic casting, there will be no hollow cores like competition kettlebells.

Cast iron kettlebell weight

Usually cast iron kettlebells do not have to be color-code because on the surface there are castings representing the weight corresponding to their sizes.

Cast iron kettlebell pros

  • Cast iron kettlebell has the advantage of being wider and slimmer arm, so it is easy to hold with 2 hands, especially with swing or squat movements.
  • The price of cast iron is usually cheaper because the core part is not arranged when casting.
  • For exercises that require two weights, cast iron kettlebells are overwhelmed because there are a range of smaller sizes.

Cast iron kettlebell cons

  • The handle section of the cast iron kettlebell has a quite large diameter, about 38mm. For those with small hands, it will be quite thick and difficult to grip even when using two hands.
  • Due to the shape of the handle being a wide arc to the sides, the kettlebell is only suitable for use with 2 hands. If used with one hand, you will find it difficult to fix the grip to keep the weight balance.
  • Because the size and handle of kettlebells are different with different weights, it can be difficult for the practitioner to constantly get used to the new grip when changing the weights. Therefore it is not used in competition.
  • With cast iron kettlebells that are lighter, the small base is more difficult to balance on the floor.

  • Reputation: refer to the number of years of operation, customer reviews as well as pictures of the company’s products. This is often shown on a website, e-commerce sites or social networking sites.
  • Price and quality: these are two associated criteria. You cannot ask for a foundry to make a kettlebell of high quality but cheap. Depending on your budget and usage needs, make your own choices.
