L’entraînement avec kettlebell peut apporter des bénéfices incroyables sur vos performances sportives et votre santé. Mais s’équiper avec un set complet de kettlebells peut être onéreux et nécessite un espace de stockage relativement élevé.

OneBell®, notre kettlebell modulable de 12 à 32kg, est la solution idéale pour les pratiquants de kettlebell qui n’ont ni le budget ni la place pour se procurer plusieurs kettlebells. 19 kettlebells en 1 pour économiser de l’espace et de l’argent.


Le principal avantage de la OneBell® est le gain d’espace de stockage. Si vous vivez dans un appartement où vous ne pouvez pas vous permettre d’aligner une dizaine de kettlebells de poids différents, la OneBell® est la solution parfaite.


Le coût d’achat d’un set de base de kettlebells (16kg, 24kg, 32kg) s’élève souvent à 200-300 euros selon les marques. Pour un set complet avec des poids intermédiaires, il faudra compter plusieurs centaines d’euros, voire plus de 1000 euros selon les marques. Avec la OneBell®, pour le prix d’un set de base vous avez 19 kettlebells, allant de 12 à 32kg par tranche de 1kg.


Vous partez en vacances ou vous voulez vous entraîner en extérieur ? La OneBell® se loge parfaitement dans un coffre de voiture : vous pouvez vous entraîner n’importe où, n’importe quand.


Contrairement à la plupart des kettlebells réglables du marché, la OneBell® a la forme d’une vraie kettlebell : vous pouvez réaliser tous les exercices balistiques et grinds. Si le temps de réglage peut être un peu plus long que sur d’autres modèles, vous obtenez en retour une kettlebell très ergonomique et totalement sécurisée.

    Franchement, rien a redire . Merci la French Cop Team pour la découverte.
    La bête a pris un peu plus de temps à arriver à cause de la fin d’année mais pour le reste, nickel!
    Facile d’utilisation et va grandement remplacer beaucoup de mes kettlebells. Peut être une deuxième bientôt, qui sait?

    Un must-have. Vraiment excellent. Le poids est bien équilibré, maintenu avec l’écrou interne sur le pas de vis, et l’énorme vis BTR du fond permet de verrouiller le tout correctement. Aucun regret d’avoir acheté et attendu, ça vaut vraiment son prix.

    La variation de charge est assez rapide, une minute environ pour faire bouger tout ça.

    Le petit point noir serait que la peinture s’écaille un peu au niveau de la jonction et fait des petits copeaux pointus. Sinon, le tout est de bonne facture.

    Great packaging and great tools for hard training!
    They’ve been great so far!
    I bought a couple of them in order to train with uni and bi-lateral exercises: they’re wonderful!
    The only thing to mention is that if you want to train by doing long sessions of swings, the handles are not suitable for that, but that’s ok, being competition style kettlebells.

    I try to not bang them too much against each other, but that’s just me 😉

    Après 2 mois d’utilisation, rien à redire sur cette Kettlebell modulable! Le tout en un parfait qui permet de moduler progressivement la charge de travail. Un must have quand on a un espace de stockage limité !

    This is a great solution for me because I train at home and have limited space available. I also appreciate the fact that you can shift in 1 KG increments with this kettlebell, while regular kettlebells are usually available in 4 KG increments. This helps more with the progressive overload in strength training. Overall it’s a great kettlebell, with a smooth handle.

What is a kettlebell?

The kettlebell is a training tool that originated in Russia. Also called "girya" in Russian, it is often described as a cast-iron ball with a handle. The particular shape of the kettlebell distinguishes it from other traditional weight training equipment such as dumbbells or Olympic barbells.

The kettlebell offers a unique approach to training, focusing on functional and versatile movements. It allows you to perform a wide variety of exercises, combining strength, endurance, stability and coordination. Training with a kettlebell simultaneously involves several muscle groups, making it an effective tool for developing overall strength and fitness.

One of the kettlebell's distinctive features is its sturdy, wide handle. This provides a firm grip and facilitates the execution of swinging, oscillating and rotating movements. The unstable nature of the kettlebell also requires greater engagement of the stabilizing muscles, enhancing coordination and balance.

The kettlebell can be used by all fitness levels, from beginners to advanced athletes. It is widely used in gyms, functional training programs, sports disciplines and even as part of physical preparation for certain operational professions.

Kettlebell buying guide

When it comes to buying a kettlebell, it's important to consider certain aspects to make the right choice for your needs and fitness level. Here are a few things to consider when buying a kettlebell. You can consult our kettlebell buying guide for more specific information.

Kettlebell compared to other weight training equipment

The kettlebell differs from other strength training equipment in several ways. Unlike dumbbells, kettlebells have an uneven weight distribution, requiring extra muscle control when executing movements. This instability places greater demands on the stabilizing muscles, which can help improve balance and coordination.

Compared with weight machines, kettlebells offer greater freedom of movement and enable functional movements that mimic everyday gestures. In addition, the variety of exercises possible with kettlebells makes it possible to work many muscle groups at the same time, which makes them an effective tool for an overall workout.

The different types of kettlebells

There are different types of kettlebells available in the market, each with its own characteristics. Here are some of the commonly encountered types:

  • Classic kettlebells : These are the traditional kettlebells, often made of cast iron, with a fixed weight. They are available in a wide range of weights, making it easy to choose the one that best suits your goals and fitness level.
  • Competition kettlebells : These kettlebells are used in official kettlebell sport competitions. They have a standardized size and weight to ensure fairness between participants.
  • Adjustable kettlebells : These kettlebells offer the ability to change the weight by adding or removing discs. They are handy if you want to progress in your training without having to buy several kettlebells of different weights.
  • Vinyl or rubber kettlebells: These kettlebells are covered with a layer of vinyl or rubber, making them more resistant and less likely to damage the floor in the event of a fall.

Choose your kettlebell weight

Choosing the right weight for your kettlebell is key to ensuring a safe and effective workout. We recommend starting with a lighter weight if you're a beginner or have no previous kettlebell experience. This will allow you to familiarize yourself with the movements and gradually build up your strength and technique.

In general, it's advisable to choose a kettlebell whose weight allows you to do between 8 and 12 repetitions of a given exercise with good technique, without compromising form. Once you've built up strength and confidence, you can gradually increase your kettlebell weight to keep progressing.

It's important to note that the kettlebell may feel heavier than other bodybuilding equipment due to its uneven weight distribution. So it's best to start with a lighter weight than you normally use with other equipment.

In conclusion, before buying a kettlebell, take the time to consider the different types available on the market, taking into account your preferences and goals. Choose a weight suited to your fitness level, and don't hesitate to consult a health professional or qualified trainer if you have any doubts.

Exercise Guide

One of the main advantages of the kettlebell is the versatility of the exercises it can perform. Here's a selection of exercises to help you get the most out of your kettlebell. You can check out our guide to kettlebell exercises for more information.

Ballistic exercises

Ballistic kettlebell exercises involve dynamic, explosive movements that exploit the inertia of the kettlebell's weight. They focus on power, coordination and muscular endurance. Here are some of the most common ballistic drills:

  • Swing: Swing is the emblematic kettlebell exercise. It consists of swinging the kettlebell between the legs, then projecting it at chest height, using the strength of the hips to generate momentum. This exercise mainly targets the muscles of the legs, glutes, abdominals and back.
  • Snatch : The snatch is a movement similar to the swing, but with a more vertical trajectory. It consists of swinging the kettlebell between the legs and propelling it upwards, ending the movement with arm stretched above the head. Snatch develops power, explosiveness and endurance.
  • Clean: The clean is a movement that consists of bringing the kettlebell from the low position between the legs to a rack position, i.e. close to the shoulder, using the strength of the hips and arm. It's a complete exercise that involves the muscles of the lower body, trunk, arms, back and shoulders.

Grind exercises

Kettlebell grinds are slower, more controlled movements that emphasize strength and stability. They develop muscular strength and endurance while improving technique. Here are some of the most popular grind exercises:

  • Press: The press consists of developing the kettlebell from the rack position to overhead by extending the arm. This exercise mainly targets the muscles of the shoulders, arms and core, developing strength and stability.
  • Squat : The kettlebell squat is a variation of the traditional squat where the kettlebell is held in front of the chest. As you descend into a squat position, the kettlebell adds an extra load that strengthens your leg and core muscles.
  • Turkish Get-Up : The Turkish Get-Up is a complete exercise that involves going from a lying position to a standing position while holding a kettlebell overhead. This exercise enhances stability, mobility, coordination and strength throughout the body.

It's important to note that these examples represent only a small fraction of the exercises possible with the kettlebell. There are many variations and combinations of exercises that can be adapted to suit your goals and fitness level.

Guide to kettlebell training

Kettlebell training offers a multitude of options and styles that can be adapted to suit your preferences and goals. Here are some of the different styles of kettlebell training. You can check out our guide to kettlebell training for more detailed information.

The different styles of kettlebell training

Sport style

The sporty style of kettlebell training is competition-oriented. It focuses on muscular endurance and precise movement technique. Participants train specifically for kettlebell sport events, such as the snatch, throw and long cycle. This style of training requires great mastery of movement and solid physical condition.

Hard style

Hard style is a training style that emphasizes strength, power and maximum muscular tension. It focuses on explosive and controlled movements, paying particular attention to breathing and body stability. Specific breathing techniques are often used to maximize the performance and power of the movements.

CrossFit style

CrossFit is a training method that integrates various disciplines, including the kettlebell. In this style of training, kettlebell exercises are combined with other functional movements, such as pull-ups, burpees and jumps. Workouts are often intense and varied, aimed at improving overall fitness, strength and endurance.

Each of these training styles offers its own benefits and challenges. It's important to choose the style that best suits your goals, personal preferences, and fitness level. In general, it is rather advisable to start with a hard style training.

The kettlebell for physical preparation

The kettlebell is a versatile tool that can be used in different areas of physical preparation. Here are some examples of its use in different contexts:

The kettlebell for operational jobs

Professions that require optimum physical condition, such as firefighting, law enforcement and the military, can benefit from kettlebell training. Functional kettlebell exercises, such as swings and cleans, can improve the strength, endurance, stamina and coordination needed for these demanding professions.

The kettlebell for combat sports

Martial arts and combat sports require a combination of strength, power and speed. Kettlebell training can help develop these specific physical qualities. Exercises such as snatches, presses, and kettlebell squats can strengthen the muscles used in striking, throwing, and defending movements.

The kettlebell for endurance sports

Although the kettlebell is often associated with more explosive movements, it can also be used to improve performance in endurance sports. Exercises such as kettlebell swings, cleans and lunges can strengthen leg, core and back muscles, which can improve the efficiency of running, cycling and other endurance activities.

The kettlebell for team sports

Team sports such as soccer, basketball and rugby require a combination of strength, agility and coordination. Kettlebell training can help develop these essential physical qualities. Exercises such as kettlebell cleans, presses, and lunges can strengthen leg, arm, and core muscles, improving performance on the court.

It's important to note that kettlebell training can be adapted to the specific needs of each sport or profession. It is recommended that you consult a qualified trainer or medical professional for personalized advice based on your goals and requirements.
