Professional competition kettlebells from 8 kg to 48 kg in best studio quality.
From one piece
Using a precision casting process, the kettlebell is produced in one piece, without any welding. This is the only way to achieve incredible product durability.
International Standards
The TREMOS Competition Kettlebells meet international competition standards in terms of shape, size, color coding, and handle diameter (35 mm). The weight is engraved on one side of each kettlebell, and the TREMOS logo is on the other.
No filler
TREMOS kettlebells up to 36 kg are not filled but cast in an individual mold, precisely adjusted to the correct weight and containing no fillers. From 40 kg onwards, the core is filled with a lead mixture in a second casting process to achieve the increased weight.
Lifetime Warranty

We are absolutely convinced of the quality of our kettlebells! That's why you get a lifetime guarantee on our Competition Kettlebells.

Key features
- Dimensions according to international standard: Competition kettlebells are all the exact same size, regardless of weight, for a perfect training experience. The handle has a diameter of 35mm.
- One piece of steel: Our kettlebells are cast in one piece, without any welding. This is the only way to achieve this incredible durability.
- Focus near the handle: Because the balls are hollow and not filled, the center of gravity is somewhat closer to the handle than with filled ones, which leads to better rotational behavior of the ball.
- Uncoated Handle: For the perfect grip, it's essential that the handle is uncoated, because only then will you have the ball perfectly in your hand.
- Handle diameter: 35 mm (+/-5%)
- Weight deviations up to approx. 200g
Kettlebell color coding:

Note: We're currently switching our product line from paint to powder coating. That's why we're offering a 10 % discount on all painted kettlebells.
What is the difference between painting and powder coating?
- Die Pulverbeschichtung ist noch robuster und widerstandsfähiger gegen Kratzer, Abplatzen und Stöße.
- Die lackierten Kettlebells matt, die pulverbeschichtete Farbe hingegen glänzend.
- Alle pulverbeschichteten Kettlebells haben auch einen imprägnierten Griff: Gleicher Halt, aber kein Rost.
Warum überhaupt mit Kettlebells trainieren?
Kettlebell Training ist mehr als nur ein Fitnesstrend – es ist eine der effektivsten Methoden, um Kraft, Ausdauer und Beweglichkeit gleichzeitig zu verbessern.
1. Ganzkörpertraining mit System
Ob Swing, Clean oder Turkish Get-Up – beim Kettlebell Training wird dein ganzer Körper aktiviert. Du trainierst nicht nur einzelne Muskeln, sondern ganze Muskelketten. Das macht dein Training unglaublich effizient.
Tipp: Schon in 20 Minuten täglich mit der Kettlebell kannst du unglaubliche Fortschritte erreichen.
2. Mehr Leistung, mehr Stabilität – auch im Alltag
Kettlebells fördern deine Körperkontrolle, Rumpfstabilität und funktionelle Kraft. Du wirst nicht nur stärker, sondern beweglicher, koordinierter und widerstandsfähiger – perfekt für Alltag, Sport oder Beruf.
3. Ideal für Zuhause & unterwegs
Kettlebells brauchen wenig Platz, sind extrem robust und liegen optimal in der Hand. Egal ob im Wohnzimmer, im Home Gym oder im Park – mit deiner Kettlebell hast du dein Gym immer dabei.
4. Kraft und Ausdauer
Kettlebell Workouts sind berüchtigt dafür, die Herzfrequenz schnell nach oben zu treiben. Je nachdem, wie du die Kettlebell nutzt, kannst du damit aber auch sehr gut Kraft und Muskelmasse aufbauen.
5. Extrem vielseitig
Die Kettlebell ist wohl eines der vielseitigsten Trainingsutensilien der Welt. Der Kreativität beim Training sind somit keine Grenzen gesetzt.

TREMOS is a sole proprietorship personally owned and managed by Konrad Adamsmair, located in Neuhofen an der Krems, Upper Austria. I founded this company, and thus the TREMOS brand, myself in 2022. As a trainer with many years of professional experience, high product quality is a major concern for me. If I don't use it, I don't sell it: I don't sell any product that I don't also train with myself.
Reviews
Competition Kettlebells

Top quality—I'm thrilled. I've already got my next kettlebell on the list 👍
As a freelance trainer, I'm very happy with the Tremos kettlebells! My clients and I use them all the time—they don't slip even with wet hands, are easy to handle, and are all the same size. Simply the best!
It's really fun to angle.
I now own pairs from 26 lbs to 61 lbs, so I am obviously completely satisfied with the quality and service at Tremos!
Hassle-free order, fast delivery, good quality of the KB
