TWISTER.CK 4-in-1 Adjustable Dumbbell Set — 44 / 66 / 88 lb, Converts to Barbell & Kettlebell

One set, four configurations. These adjustable dumbbells connect via a barbell rod to become a full barbell, or reconfigure as a kettlebell — giving you a complete strength training toolkit in a compact footprint. The polyethylene outer shell encases an iron, clay, and sand core for floor-safe, odor-resistant durability. Fast-spinning adjustment nuts lock weight plates securely in seconds, and the textured non-slip handles reduce hand fatigue through every set.
