About this item FUNCTIONAL STRENGTH TRAINING: Kettlebell training involves every day, such as lifting heavy bags, pulling open doors, and reaching things that are up high. While improving your strength, you are also getting a cardio workout with kettlebells. NO FILLER OR WELDING: Each Kettlebell is individually cast as one solid piece instead of welding parts together. The mold has a hollow core cast to precisely the correct weight ensuring accuracy compared to other molds. COLOR CODED WEIGHTS: The Competition Style Kettlebell comes in a variety of color-coded weight increments from 8 KG to 40 KG, with little fluctuation in diameter, maintaining consistency in feel as you move up to higher weights. DURABLE CONSTRUCTION: The Kettlebell is cast from heavy-duty steel with non-welded handles, no filler, or rattle to help improve overall strength and power. DIMENSIONS: The kettlebells are uniform in 8.3-in diameter, 11.4-inch height, and a 35 mm handle thickness, allowing you to train the same movement while also increasing or decreasing weight to cater to your routine.
