Introduction

My name is David Williamson and I am a professional personal trainer and fitness coach for over 20 years. Today I want to share my knowledge with you about Kettlebells.


Kettlebells have become hugely popular in recent years. They are a fantastic piece of functional fitness equipment, compact, versatile, perfect for building strength, endurance and power.


In this guide, I will explain what kettlebells are, how they work, the different types you can buy, the benefits, and how to choose the right kettlebell for you - plus my top 5 kettlebell exercises for home workouts.

What is a Kettlebell?

A kettlebell is a cast iron or steel weight in the shape of a cannonball, with a flat bottom and a handle on top. This design is unique and shifts the weight's centre of gravity away from your hand, making it a totally different function to a dumbbell or barbell.


The kettlebell originated in Russia in the 18 th century, are now imbedded in strength and conditioning, CrossFit, and functional fitness training industry.

How do Kettlebells work?

Kettlebells provide resistance for strength and power training, their design allows for dynamic, swinging movements as well as traditional lifts.


This means they can combine cardio and strength training in the same workout, raising your heart rate whilst building muscle, they can also be utilised in various multidirectional sports, golf and martial arts. The offset handle position also greatly strengthens your grip and core.
