Key takeaways
- Pick a cast-iron kettlebell for the best overall buy. Look for a wide handle that is smooth, with no sharp seams.
- Choose a competition kettlebell for swings and long sets, because the bell is the same size at every weight.
- Choose an adjustable kettlebell for small spaces, since one bell gives you several weights with a dial or pin.
- Choose a vinyl kettlebell if you are a beginner, because its soft coating protects your floors.
- Many women start swings with 8 to 12kg and many men with 12 to 16kg, going lighter for presses and Turkish get-ups.

The short answer
The best kettlebell for most people is a cast-iron kettlebell. It is one solid piece of iron with a wide handle. Pick the weight that suits your level, not the heaviest bell you can find.
Bez's coaching advice: many women start swings with 8 to 12kg, and many men with 12 to 16kg. Go lighter for presses and Turkish get-ups. If you cannot keep a flat back, go lighter still. Start light, then add weight as your form gets better.
Which type is for you?
- Cast-iron kettlebell: Best overall. Great if you want one bell for every move, from swings to presses.
- Competition kettlebell: Best for swings and long sets. Same size at every weight, so your hands learn one shape.
- Adjustable kettlebell: Best for small spaces. Several weights in one bell, so you can switch quickly.
- Vinyl kettlebell: Best for beginners. A soft coating protects your floors, and it comes in lighter weights.

How to choose a kettlebell
Bez checks six things before he picks a kettlebell. Run through them before you buy.
| What to check | What good looks like | Why it matters |
|---|---|---|
| Weight for your level | Many women start swings with 8 to 12kg. Many men start with 12 to 16kg. | Too heavy breaks your form. Too light won't challenge you. |
| Handle width and finish | A wide handle with a smooth finish and no sharp seams. | Your hand needs room. Sharp seams can pinch and rub. |
| Flat base | The bell sits flat and stays put when you set it down. | A flat base is stable and safe. |
| Consistent size or compact | Competition bells stay the same size at every weight. Adjustable bells are compact. | Same size feels familiar at every weight. Compact fits small spaces. |
| Floor protection | A soft vinyl coating helps protect your floor. | Coatings can wear with heavy use. |
| Space for bells | Count how many bells you have room for. | One adjustable bell can cover several weights. |
Start lighter than you think. Go lighter for presses and Turkish get-ups too. If you can't keep a flat back, drop the weight. Adults should do muscle-strengthening activity on at least 2 days a week (strong evidence, NHS guidelines). Kettlebell training can improve strength and fitness in the same session (moderate evidence). New to swings? Read our kettlebell workout for beginners.
Use Your Kettlebell Safely and Get Better Results
Kettlebell training can improve strength and fitness in the same session (moderate evidence). Use it well and you will get more from every workout.
Adults should do muscle-strengthening activity on at least 2 days a week (strong evidence, NHS guidelines). Keep it simple and do it often.
Start with the basics. Learn the hip hinge before you lift anything heavy. Your hips do the work, not your arms. Good form beats heavy weight every time. Film a set from the side to check your back stays flat.
Bez's starting weights: many women start swings with 8 to 12kg, and many men with 12 to 16kg. Go lighter for presses and Turkish get-ups. If you can't keep a flat back, go lighter.
Follow these safe-use rules every time:
- Learn the hip hinge first.
- Keep a flat back.
- Swing with your hips, not your arms.
- Clear space around you.
- Train on a non-slip floor.
Progress slowly. Add weight or reps when the last set feels easy and your form stays clean. Rest well between sessions so you recover. Finish feeling strong, not wiped out. Read more on progressive overload and try a kettlebell workout for beginners.
