5 Common Mistakes with Adjustable Kettlebells (and How to Avoid Them)

Do you ever find yourself using the same weight for every kettlebell exercise? Or needing to stop mid-workout just to reconfigure your kettlebell? Adjustable kettlebells are a great convenienceā€”but they come with a few real pitfalls. In this article, weā€™ll go through 5 common and realistic mistakes people make (and how to avoid them with simple tweaks).

1. Using the Same Weight for Too Many Exercises

People with adjustable kettlebells often stick to a middle weight (like 16 or 20 kg) for everything: swings, cleans, pressesā€¦

What happens: poor technique, limited progression.

How to avoid it: learn which exercises truly require different loads, and switch weights more oftenā€”even if it takes effort. It helps to note 2ā€“3 typical weight setups based on your training type.


2. Adjusting the Weight ā€œBy Eyeā€ Without Checking Symmetry

Many adjustable models, especially those with internal plates or blocks, can end up unbalanced if not assembled carefully.

What happens: weird rotation, wrist or forearm pain, joint discomfort.

How to avoid it: take a few seconds to check the symmetry. The weight should be balanced and stable. If you hear rattling or feel vibration during swings, somethingā€™s likely off.


3. Underestimating Adjustment Time Mid-Workout

You start an EMOM (Every Minute on the Minute) or ā€œfor timeā€ workout full of energyā€¦ then end up wasting time adjusting the kettlebell.

What happens: stress, lost rhythm, lower intensity.

How to avoid it: prep your weight blocks beforehand, or design the workout to minimize weight changes. For example, use constant-load AMRAPs or alternate only between two settings.


4. Training on the Wrong Surface

At home, people often train on tile, hardwood, or unstable mats. A poorly placed kettlebell can slide or damage the floor.

What happens: injury risk, damage to your space.

How to avoid it: use a stable, non-slip surface. Even a firm mat can make a big difference. If switching rooms or flooring, test with light swings first.


5. Neglecting Maintenance of the Internal Mechanism

Threaded or slide-lock systems can start grinding or jamming if not cleaned. Dust and sweat build up over time.

What happens: adjustment becomes slow or even fails.

How to avoid it: every 5ā€“10 sessions, disassemble, clean, and dry your bell. No oil neededā€”just a dry or slightly damp cloth. Some models also tolerate a gentle burst of compressed air.


Conclusion

Adjustable kettlebells are a powerful toolā€”but only if you understand their quirks. With a few small adjustments in how you use and care for them, youā€™ll train more efficiently and get better results.
