The Adjustable Kettlebell works as a weight resistance and counterbalances for a variety of upper and lower-body exercises. Divided into six drop cast-iron weights weighing 4.6 LB to 6 LB, you can work up to 40 LB all in one kettlebell. The simple quick-lock design makes removing and adding weight quick and easy while ensuring the discs stay secure during your workout. The 28 mm smooth handle provides a comfortable and secure grip when lifting and swinging. This 7-in-1 Adjustable Kettlebell is ideal for performing explosive exercises that work major muscles, build power, and burn body fat.
