If you’re just getting started with kettlebell training, picking the right one can make a huge difference in how enjoyable and effective your workouts feel. With so many styles and sizes available, it’s easy to overthink the decision. This guide will help you choose your first kettlebell, find the right weight, and know when it’s time to go heavier.
Start with the Right Weight
You don’t need a full rack of kettlebells to get strong. Just one well-chosen kettlebell is enough to build real strength and conditioning.
Here’s a good place to start:
- For most women: 18 to 26 pounds (8 to 12 kilograms)
- For most men: 26 to 35 pounds (12 to 16 kilograms)
If you’re completely new to training, it’s better to start lighter and focus on mastering form. If you already have experience with strength work, lean toward the heavier side of the range.
Choose the Right Style of Kettlebell
This is where most beginners get tripped up. All kettlebells are not the same, and the style you choose can either support your training or make it more frustrating.
Start with cast iron. These are the most balanced, durable, and comfortable for general use. As the weight increases, the size of the bell gets larger. They’re ideal for swings, squats, and presses.
Look for a quality powder-coated cast iron kettlebell. The powder coat gives the bell a smooth, grippy finish that won’t chip easily and can withstand years of use. It helps the kettlebell move smoothly in your hand during cleans and snatches and is much more durable than painted finishes. A well-made powder-coated bell can last a lifetime.
Look for a kettlebell that is as close to a perfect sphere as possible. A rounded shape will rest more comfortably on your forearm during cleans and presses and will help prevent bruising on your wrists. Flat-sided or oddly shaped bells can dig into your arms and make you dread certain lifts.
Skip vinyl or plastic-coated kettlebells unless you're doing very light work. The coating might seem grippy, but it actually prevents the bell from rotating in your hand—something you need for moves like cleans and snatches. This can lead to blisters or torn skin. They also tend to be poorly balanced and wear out over time.
Competition kettlebells are also a good choice, especially if you plan to progress into more technical movements. These have a standardized size and shape regardless of weight, which helps with consistency. But they’re not necessary for beginners.
What About Adjustable Kettlebells?
Adjustable kettlebells might seem like a smart way to save space and money, but they come with trade-offs.
Most adjustable designs are bulky and not shaped like a true kettlebell. The awkward dimensions can throw off your balance and rhythm, especially during swings, snatches, and cleans.
If you do choose an adjustable model, look for one that keeps a consistent center of gravity and has a rounded shell. Avoid anything with a clunky shape or rattling parts.
They can be useful for squats, presses, and deadlifts, but not ideal for dynamic movements. You’re better off starting with one solid, well-shaped cast iron bell and adding more weights over time.
When Should You Scale Up?
At some point, your starting kettlebell will no longer challenge you. That’s a good thing. It means you’re getting stronger.
Here are some signs it’s time to move up in weight:
- You can perform 15 to 20 reps of swings, squats, or cleans without losing form
- Your grip is not challenged during your sets
- You finish workouts feeling like you could have done a lot more
Aim to scale up gradually. Try to increase in increments of around 9 pounds or 4 kilograms if possible. You don’t need every size. Just one or two heavier options can open up new training possibilities.
The Bottom Line
Start simple. Choose a cast iron kettlebell with a smooth, spherical shape and a weight that challenges you without breaking your form. Avoid gimmicky shapes or oversized adjustable models unless they’re well-designed.
This one decision sets the foundation for months of solid training.
