Built to Last
The innovative dual-cast process leaves the competition kettlebell hollow in the middle-that means no rattle of doom after repeated drops. The bells are cast as one piece with no welds to last a lifetime. Perfection!

- ELEdmundo L.Verified BuyerRated 5 out of 5 stars6 days agoBest Kettlebell Purchase I ever made
This is my second 16kg competition kettlebell from Bells of Steel. I own several (8kg for my daughter and wife, a pair of the 12 kg, a 14 kg, a 20 kg and a pair of the adjustable 32 kg and now, a pair of the 16kg). I rotate my kettlebells between my gym at the office and in my home. It gives me flexibility in training and the bells give me the needed workout when time is short. The pairs allow me to do more bilateral workouts and boy, these bells give you a lot of mileage. I also weighed these bells and their weights are really very close if not exactly as they are marked.
I still have some cast iron kettlebells (24kg, 28 kg, 32 kg and 40kg) from BOS and other sellers but these competition kettlebells are my go to as the size remains the same and so the technique you develop is more consistent. Thank you BOS for your high quality kettlebells.

I have purchased multiple Competition Kettlebells from Bells or Steel. I have 2 - 8 KG, 2 - 12 KG, 2 - 18 KG,1 - 24 KG, and 1 - 28 KG. I purchased these because I am a certified Kettlebell Trainer, I do a ton of 2 bell swings and no gym around me has enough Kettlebells for my needs. These are amazing quality and i love how they are all the same size so no matter the weight they fel the same in my hand. Another huge benefit of Bells of Steel is the shipping is included. The package always comes in pristine condition and the customer service is awesome. I recommend them to everyone I teach Kettlebells to.

The B.o.S. Crew - FPFranklen P.Verified BuyerRated 5 out of 5 stars6 months agoThe Way of the Iron: A Buddhist Reflection on Heavy Kettlebells
In Buddhism, we embrace the Middle Way, balancing strength with wisdom, discipline with ease. Heavy kettlebells embody this path—offering both a test and a teacher.
To lift is to be present. The weight demands full awareness; there is no room for distraction, no place for the mind to wander. A kettlebell swing is a meditation in motion—inhale, brace, explode—exhale, release, reset. Just as we cultivate mindfulness through breath, we cultivate strength through repetition.
Heavy kettlebells teach impermanence. Fatigue comes, then passes. Strength grows, then is tested again. The struggle is neither good nor bad—it simply is. In surrendering to the moment, we find power.
My clients, like myself, have come to love these iron monks. They break us down, only to build us up stronger—physically, mentally, and spiritually. To lift heavy is not just to train the body, but to discipline the mind and forge the spirit.
In each rep, we meet ourselves. And in that meeting, we grow. This is the way of the iron.
