A kettlebell is an essential tool for working out. In fact, be it a regular for strength training, or extensive yoga; kettlebell can be a popular tool used in most workouts. Even though kettlebells tend to look a little intimidating, it is a powerhouse of incredible potential and can give your exercise that extra pump. A ‘flow’ is a term extensively used nowadays, while it is nothing but a series or a sequence of a particular kind. However, having a proper kettlebell flow means you follow up one exercise after the other, creating a sequence of a sort.
