Dumbbells are great for strength training but they do take some space. The STAKRBELL is a flat stackable dumbbell with 4lbs and 6lb weights that link together to turn into 4lb, 6lbs, 8lbs, and 10lbs weights. These dumbbells have polyurethane coating.

STAKRBELLs can be easily stored away, e.g. inside the Deck 2.0 with your resistance bands. These weights also don’t roll, which is convenient.
