Exersci Cast Iron Adjustable Kettlebells

Meet the Exersci Cast Iron Adjustable Kettlebell — a compact, heavyweight training solution that replaces a whole kettlebell rack in a single, versatile piece. Designed for strength, conditioning, and functional fitness, this kettlebell adapts as you progress — so you don’t have to keep buying new weights.

Two Models — Tailored to Your Strength Level

8 kg – 16 kg – ideal for beginners to intermediate lifters, perfect for kettlebell swings, goblet squats, Turkish get-ups, and more.

16 kg – 24 kg – built for intermediate to advanced users, excellent for heavier swings, cleans, presses, snatches, and conditioning circuits.

Each model adjusts in 2 kg increments, giving you fine-tuned control over your load and progression.

• Solid Cast Iron Construction – built like a classic kettlebell for durability and consistent feel. 
  
• Space & Cost Efficient – replace 5+ fixed-weight kettlebells with one adjustable unit, saving floor space and money over time. 
  
• Compact & Home-Gym Friendly – dimensions roughly Ø 18 cm × H 26 cm, making it easy to store or fit into tight spaces. 
  
• Secure Internal Locking Mechanism – ensures weight plates stay firmly in place during swings, presses, cleans, and more. 
  
• Flat, Stable Base – great for putting down between sets or using for exercises that start from the floor.
• Please note: this kettlebell is not designed to be dropped; doing so may damage the internal mechanism. When finished exercising, place the kettlebell down carefully
