PTs confirm: These are the 7 most effective kettlebell workouts of all time to build strength, muscle and tone

If there's one sure-fire way to up the ante on your workouts, it's adding in a fiercely effective piece of kit. In this case, we're talking about the classic kettlebell. Once only seen in gyms, the kettlebell is now a ubiquitous piece of kit in weights rooms and home gyms alike.

Essentially a weighted ball with a handle at the top, the kettlebell has been a mainstay in gyms across the world since the early 20th century, when Russian fitness pioneer Pavel Tsatsouline introduced them to his exercises. And as far as effectiveness goes, they're pretty much unmatched.

"The unique shape and weight distribution of a kettlebell challenges your balance and stability while engaging your core during a lift, setting them apart from traditional dumbbells and barbells," explains regional physiology lead at Nuffield Health, Becky Scott. "They add a functional element to your weightlifting routine that's hard to recreate with other equipment."

While some of us may not have used one, the benefits of working out with kettlebells speak for themselves: studies (such as this one, published in the Journal of Human Kinetics) show that they can be used to improve strength, aerobic power and overall physical fitness - quite the trifecta. Similarly, other research points to the kettlebell being a useful tool in strength and conditioning generally, although it is noted that the literature is limited.

And we know more generally that adding weight to our training moves is a winner, in terms of building strength and improving bone density and health - particularly vital for women approaching peri-menopause, when our risk of developing osteoporosis is greater.

Want to build muscle? These are officially the best kettlebell workouts of all time

What is a kettlebell?

For the uninitiated, you'll probably have seen a kettlebell before, even without realising it. "A kettlebell is a great piece of fitness equipment - it looks like a cannonball with a handle," says women’s health and fitness expert and founder of Fit Mama, Mari-Carmen Sanchez-Morris. "It’s great for building strength, improving endurance, and enhancing our cardiovascular fitness."

What are the benefits of working out with a kettlebell?

So, why should we be using a kettlebell in our workouts? Known to improve strength, endurance and flexibility in one fell swoop, kettlebells are highly versatile.

"Unlike traditional dumbbells, the design of the kettlebell shifts the centre of gravity away from your hand, making it ideal for dynamic, swinging, and multi-directional movements," explains personal trainer and founder of Dare to be Fit, Grace Reuben. "It’s been a staple in strength and conditioning for years, thanks to its versatility and effectiveness." Now - let's dig into the benefits.

1. They build strength

First and foremost, you can build some serious strength with a kettlebell. "Loading up moves such as cleans and swings not only boosts functional fitness (making everyday activities easier) but also engages multiple muscle groups simultaneously," explains personal trainer and health coach Dewayne Gross. "These types of movements, known as compound moves, are extremely effective for building muscle and functional strength."

2. They're great for core strength

"The unique shape of the kettlebell shifts the centre of gravity, which means your body has to work hard to engage stabilising muscles more than traditional weights," says Sanchez-Morris. "This helps to improve our core strength, balance, and coordination."

3. They're accessible

As well as being a compact piece of kit, a single kettlebell can replace multiple gym machines, making it ideal for small spaces or at-home workouts. Plus, they're suitable for all levels of fitness, so you can invest safe in the knowledge that you're not going to out-strengthen the weight.

4. They improve cardiovascular fitness

Not only can kettlebells help you build serious strength, but they'll improve your cardiovascular fitness, too. "High-intensity intervals with kettlebells elevate your heart rate quickly, offering similar cardio benefits to running, but with added strength-building," agrees Gross. "Additionally, the combination of strength and cardio creates a poweful afterburn effect, boosting metabolism for hours post- workout."

How many times a week should I work out with a kettlebell?

As with working out generally, how often you do kettlebell exercises will depend on your current fitness level and long-term goals. That said, the experts agree that as a general rule of thumb. two to four times per week is ideal.

"Beginners might start with two or three sessions weekly to allow time for recovery, but for those who are more experienced you could increase to four sessions," advises Sanchez-Morris. "Kettlebell training can be intense, so it’s important to give your muscles time to recover, especially if you're doing full-body workouts. Listen to your body, focus on proper form, and complement kettlebell training with rest days or other types of exercise like stretching or light cardio to stay balanced."

Who are kettlebell workouts suitable for?

"Kettlebells are great for all abilities," says Sanchez-Morris. "Beginners can use them to build strength and coordination with simple movements, while those who are more advanced can incorporate them into high-intensity, full-body workouts. They’re perfect for people looking to improve functional fitness, as the dynamic movements mimic everyday activities. Kettlebells are also excellent for busy individuals because they allow for quick, effective workouts. 

"They are also great for pregnant, pre, post natal women as they help strengthen the core, back, and pelvic floor muscles, which are crucial for supporting the body during pregnancy and preparing for labor. The functional movements improve balance and stability, which can help counteract changes in posture as the body adapts to a growing bump. Kettlebell exercises are also low-impact, making them joint-friendly."
