Kettlebells are cast iron weights ranging from 5 lbs to over 100 lbs, shaped like a ball with a handle for easy gripping. They offer a different kind of training using dynamic moves targeting almost every aspect of fitness – Endurance, strength, balance, agility and cardio endurance.
Kettlebells are different than dumbbells. With a dumbbell, the center of gravity lies in your hand but with the kettlebell, the center of gravity lies outside of your hand, which means it can change depending on how you’re holding it and moving it.
The momentum of many kettlebell movements creates centrifugal force, focusing more attention on the muscles used for deceleration and stabilization. This type of multi-directional movement mimics real life movements such as swinging a suitcase to put it in an overhead bin, for example.
Dumbbells are great for building muscle and strength with slow, controlled movements while kettlebell training involves the entire body and focuses on endurance, power and dynamic movement.
Increased core strength, endurance, and balance.
Increased bone density from bearing weight.
Decreased back pain due to the back being activated during swings.
Simplicity due to the fact you only need one piece of equipment.
Time efficiency because of training multiple fitness components at the same time (cardio, strength, balance, stability, power, and endurance).
