Introducing the KettleBull.  A DIY kettlebell made from your own  Bulgarian Training Bag.  The KettleBull provides another inexpensive alternative to high priced kettlebells.  Swings can be performed with one or two hands. The KettleBull snatch offers a safe and softer alternative to slinging the iron kettlebell.  Filled with sand you can safely build up your confidence while building strength, explosiveness, stability, and balance.
