The kettle bell is a kind of training equipment, which originated in Russia and has a long history. This is a traditional Russian fitness equipment. When the lighter kettle bell is used for faster and more repetitive training, the kettle bell training presents the characteristics of aerobic exercise.
This is aerobic exercise, which takes some time and needs sufficient oxygen supply to support the exercise. When heavy kettlebells are used for slow strength training with low repetition, kettlebell training is often anaerobic. Anaerobic exercise involves rapid and intense muscle contraction, leading to muscle fatigue and lactic acid accumulation.
