Why use a kettlebell when training?

The kettlebell allows you to work several muscle groups simultaneously, making it the ideal tool for a complete and effective workout.

Thanks to its versatility, it offers a wide range of exercises and combinations, allowing you to tailor your workout to your objectives. Whether you want to strengthen your muscles, lose weight, improve your endurance or boost your athletic performance, the kettlebell is suitable for all levels and all expectations.

Why does the kettlebell have a rubber base?

Thanks to its rubber coating, the kettlebell can absorb shocks and prevent scratches on your floors. It's a quality solution for risk-free training.

Beware of dropping the kettlebell

For safe use and to avoid damaging the floor or disturbing your downstairs neighbours, we recommend using the 4 kg kettlebell with the rubber mat (part no: 8651539), which makes it safe to drop.

How to store your kettlebell

Protect your floor by storing your kettlebell indoors, on a rubber mat (part no: 8651539), to prevent damage caused by damp. The rubber layer of the kettlebell protects the cast iron, which can be sensitive to moisture.

Our trainer's advice for improving your training (2/2)

For each exercise, start with the lowest number of reps (ensure that you don't go until failure, and leave a margin of 2 reps compared to your maximum), then increase by one rep per week until you reach the higher number in the recommended range. You can then increase your weight.
