Unlike a dumbbell or barbell, the kettlebell’s centre of mass is offset from the handle. This means the weight constantly pulls against your hand and requires not only strength and co-ordination, but also the use of the other muscles through your arms, shoulders and your core stabiliser muscles. You use around 600 muscles in a workout and exercise your cardiovascular system, too – it’s definitely a total body workout.

And you don’t have to be super strong to train with kettlebells. They come in different sizes and weights, starting at 4kg and going right up to a muscle crunching 48kg. Unlike standard weights, which are lifted carefully and slowly, kettlebells are flung around with seemingly gay abandon. You swing them, pump them and pass them from hand to hand. It’s a monster workout and some trainers reckon an hour of kettlebells will shed a mammoth 1,500 calories (compared with 300-400 for normal weightlifting or an aerobics class).

“A kettlebell class will supercharge your fitness and melt your unwanted fat,” enthuses one Kettlebells trainer in the Daily Telegraph. “You’ll bust your belly fat, lose your love handles and feel fantastic, energised and strong. Keep it up for 30 days and you can drop a dress size.”
