A kettlebell is a type of free weight looking like a ball with a handle, varying in sizes. A kettlebell offsets the centre of gravity, meaning that the body has to work harder to maintain balance. A kettlebell can help strengthen different muscles as well as working your heart and lungs.
Kettlebell training can increase core stability and combines strength training with cardio training.
The kettlebell enables easy transitions between exercises which can be very effective for weight loss due to the increased level of intensity.
