If you've spent any time in a gym, you've probably seen plenty of fitness fads revolving around some new or redesigned piece of exercise equipment. You've probably also noticed it isn't long before this new piece of equipment disappears from the gym, or if you found yourself owning one, is relegated to the basement.
But one piece of exercise equipment has been around for hundreds of years and is still actively used in gyms and in the homes of fitness buffs: the kettlebell. And its continued existence and increasing popularity are not only due to its functionality, but also its combination of cardio and strength training.
While you may know the kettlebell as that strange cannonball-shaped weight you've seen but never tried, don't be put off by it. It's nowhere near as intimidating as you imagined. Keep reading to find out why it maintains a place of respect in the gym.
When we're talking total body, the kettlebell is one of the best pieces of equipment in the gym.

A Brief History of the Kettlebell
The style and techniques of kettlebell lifting used today come directly from Russia. The original purpose of these weights was not strength training, though. They were intended as counterweights for grains and produce, using poods as the unit of measurement. Kettlebells continues to be measured in poods, with one pood equaling approximately 36 pounds, or about 16 kilograms.
Over time, people noted that those who regularly handled the counterweights developed significant strength and realized these weights could be used for physical fitness as well.
In 1948, elite Soviet military forces began regularly using the kettlebell as a key piece of equipment in their physical training arsenal. That same year, kettlebell lifting became the Soviet Union's national sport. But it wasn't until 1985 that rules, regulations and weight categories were fully established, followed by the first national kettlebell championship in Lipetsk, Russia.
Why It's an Effective Fitness Tool
The Russians aren't alone in their appreciation of the kettlebell's fitness benefits, however.
Annie Galovich, the fitness manager at Equinox in Greenwich Village, New York, and a certified kettlebell trainer, says the kettlebell has grown in popularity because it's fun to work with and provides a total body workout.
"It feels purposeful," Galovich says. "You pick something up, and it feels applicable, using almost every muscle in your body."
When used correctly, the kettlebell can stimulate every muscle fiber in the body and provide the two-in-one combination of pure strength and cardio training. And it has advantages the dumbbell just doesn't.
"The kettlebell isn't in the center of mass like a dumbbell is in your hand, so it generates force from the ground and strengthens your core," Galovich says.
The kettlebell’s exercise range generally follows the pattern of the pick-up, deadlift, snatch and swing. In other words, the pick-up from the floor, the deadlift by folding your core and legs, and then unfolding for lift off, snatching by positioning your arm and hand in preparation for the final motion, the kettlebell swing.
Galovich recommends incorporating kettlebells into the beginning of workouts after an appropriate warm-up, as it incorporates the entire body and increases your heart rate.
Before You Swing That Kettlebell
Kettlebells are, by nature, designed for intense, total-body movements with a lot of force and can be used in almost any exercise. But the kettlebell is no fad. It needs no marketing and promises no overnight answers. Instead, it offers the opportunity for rigorous training and exercises.
Chris Marhefka, founder and president of Body By Boris Fitness and Training in Gainesville, Fla., specializes in group training boot camps and has found the kettlebell to be one of the most effective pieces of fitness equipment — when used properly.
"People can abuse the kettlebell because it moves smoothly with the body," Marhefka said. "But it adds instability, engaging your core and a lot of different muscle fibers, so users need to be cautious of form."
Marhefka credits the rise in popularity of training with kettlebells to their simplicity and efficiency.
"Kettlebells have been around for a long time, but we've seen a big spike in functional training with boot camps and crossfit training," Marhefka said. "Kettlebells really fit into this shift in functional training because of their multipurpose capabilities."
Marhefka says it's important to learn how to properly use kettlebells before you start training with them. There's a greater chance of injury when using kettlebells than dumbbells because everything is free moving. Additionally, people tend to use heavier weights when using kettlebells, increasing their risk of injury.
Kettlebells are most effective at targeting the muscles along the posterior chain — the muscles on the back side of your body. When standing with the knees slightly bent in a half-squat, kettlebell exercises create a push in energy through the legs and up through the back producing a total body movement that lifts every muscle away from the ground.
Kettlebells Are Here to Stay
As more people tap into the idea that fitness needs to be a priority, they'll find that kettlebells aren't intimidating after all and will learn how to successfully use them.
"We've taken on a mentality of total body conditioning," Marhefka says. "And when we're talking total body, the kettlebell is one of the best pieces of equipment in the gym."
And unlike those latest and greatest fitness fads, the kettlebell is one piece of equipment that is not going anywhere — except when you're swinging it, of course.
