Kettlebell FAQs

Whether you are a kettlebell advocate or have never picked one up, we’re here to answer all your questions. In this section, we have rounded up and answered all the frequently asked questions about kettlebells for you. Let’s get swinging! 

What is a kettlebell? 

A kettlebell is a cast-iron or cast-steel ball with a handle attached to the top and can be used for strength training and weight loss exercises. Kettlebells are typically used for ballistic exercises that combine cardio, strength and mobility.

What are kettlebells good for? 

There are so many benefits when it comes to training with kettlebells. Some of these include: 

  • Functional fitness: Kettlebell exercises mimic real-life movements to help improve strength, flexibility and coordination. 
  • Full-Body engagement: Unlike isolated weight training, kettlebell exercises simultaneously engage multiple muscle groups. 
  • Efficiency: If you struggle for time in the gym, adding kettlebell exercises into your workout will help you save time as they burn calories while building muscle. 

Types of kettlebells 

There are a few different types of kettlebells available on the market, and depending on your environment, goals and experience levels – you may want to select a specific type. Here is a breakdown of the different types of kettlebells available.

Jordan Fitness Competition Kettlebells

Steel kettlebells: Best fit for endurance training and precise movement control, steel kettlebells are also known as competition kettlebells. They are uniform in size regardless of weight. Still, they are typically colour-coded so users can easily identify weight and have a smooth handle for easy transitions.

Cast Iron: Made from cast iron, this is the traditional form of a kettlebell and kettlebells of this variation can differ in size as the weight increases. Usually, cast iron kettlebells have a textured handle for better grip. They are used in general strength training, CrossFit and key exercises, such as kettlebell swings. 

Rubber: With rubber dumbbells, you will find they are made with cast iron or steel at the core and feature a rubber coating. This rubber coating helps to protect the floor from damage, reduces the noise when placed down and is ideal for home gyms or spaces where the flooring needs to be protected.

Benefits of kettlebell training 

1. Full-body workout efficiency

Kettlebell movements engage multiple muscle groups at once, helping you to combine strength, endurance and flexibility. In one motion, exercises like swings, snatches and Turkish get-ups target the core, legs, shoulder, and back. What more could you ask for? 

2. Improved strength and power

The dynamic nature of kettlebell exercises helps build functional strength and explosive power, which is great for those looking to improve their explosive power in sports like CrossFit. Grip strength is also enhanced due to the off-centred weight distribution. 

3. Cardio and fat-burning benefits

High-intensity kettlebell workouts increase heart rate, making them a great option for those seeking a new cardiovascular workout. Exercises like kettlebell swings provide strength and aerobic benefits, leading to high-calorie burn. 

4. Enhanced mobility and flexibility

To enhance your mobility and flexibility, you don’t have to reach for the resistance bands; simply pick up a kettlebell. There’s a whole host of kettlebell movements that can be used to promote greater joint mobility, especially in the hips and shoulders. 

5. Time-efficient training

Usually, a kettlebell workout can be completed quickly whilst still being effective, which is great for time-poor people who want to combine strength, cardio and mobility in one session.

Common kettlebell training mistakes and how to fix them

Making sure your form is perfect is a key part of training and will ensure you don’t injure yourself and maximise your workout results. At FitKit, we are experts in fitness equipment and have outlined some of the most common training mistakes when it comes to kettlebell exercises so you don’t make a crucial mistake. 

Poor grip: Make sure you have a secure hold to prevent slipping. If your current kettlebell doesn’t have a textured handle, or you have sweaty hands, use chalk or swap out the kettlebell for a textured handled option. 

Overusing arms in swings: Make sure you drive from your hips when performing a kettlebell swing, which will help activate even more muscles throughout the exercise. 

Lifting too heavy too soon: It can be challenging when you are enthusiastic and motivated to start with heavy weights. However, using too heavy weights can impact your form and cause injury, so make sure you scale up your weight as you progress. 

Neglecting the core: The beauty of kettlebell exercises is that they offer more muscle activation, with the core being a key component. Make sure you brace your core for stability with every exercise.
