The kettlebell is a cast-iron or cast steel ball with a handle attached to the top (resembling a cannonball with a handle). It is used to perform many types of exercises, including but not limited to ballistic exercises that combine cardiovascular, strength and flexibility training. They are also the primary equipment used in the weight lifting sport of kettlebell lifting.

You don’t need memberships or fancy equipment to get fit, lean up, or add on muscle. Just your hands, some willpower and a kettlebell.
With a kettlebell you can move the most amount of weight in the shortest amount of time, meaning less time training and more time enjoying your body of work.
A black cannonball with a cast-iron handle? No matter who you are, kettlebells demand respect.
