GymSets Cast Iron Kettlebells

Durable Cast Iron Kettlebells for Strength, Conditioning & Full-Body Training

GymSets Cast Iron Kettlebells are built for strength training, functional fitness, conditioning and full-body workouts. Made from durable cast iron, they provide a solid, balanced feel for swings, squats, presses, carries and other kettlebell exercises.

Solid Cast Iron Durable construction designed for repeated strength and conditioning sessions.
Wide Ergonomic Handle Comfortable grip with room for controlled one- and two-handed movements.
Flat Stable Base Keeps the kettlebell stable during storage and floor-based exercises.
Easy Weight Identification Stamped weight markings and coloured handle bands make each weight easy to recognise.

Built for Strength & Conditioning

The balanced cast iron construction makes these kettlebells suitable for swings, goblet squats, deadlifts, presses, rows, carries and kettlebell circuits. They are equally suited to heavier strength work and faster conditioning sessions.

One piece of equipment. Dozens of exercises. Kettlebells provide a compact way to train strength, power, endurance and conditioning without filling your gym with bulky equipment.

Comfortable, Controlled Grip

The wide handle provides space for both one- and two-handed exercises, while the balanced weight distribution helps the kettlebell feel controlled through swings and transitions. A durable finish also helps protect the cast iron during regular use.

Compact & Easy to Store

The flat-bottom design keeps each kettlebell upright and stable when not in use, making them ideal for home gyms, PT studios and commercial training spaces. Clear weight markings and coloured handle bands also make different weights quicker to identify.
