Kettlebells exploded on the strength and conditioning scene over 20 years ago and they remain very popular with strength and power athletes. Kettlebells are an incredibly versatile tool, allowing you to perform everything from traditional barbell/dumbbell exercises to specialized kettlebell movements. Heavier kettlebells can be used to enhance your strength, muscle mass and power work.
Kettlebells also have benefits that many people don't often think about. First, their design makes them very shoulder-friendly, which is important for a lot of athletes. Second, they develop the muscles of the core and thoracic spine. Third, they can be lifted rhythmically, which makes them ideal for conditioning. Finally, they develop mobility and athleticism due to the physical skill that many kettlebell-based exercises require.
