The ILUS CPU 12-Side Dumbbell Set is ideal for progressive strength training with maximum durability. Each dumbbell is coated with a cast urethane (CPU) coating, which offers high resistance to impacts and drops. The dodecahedral-shaped heads prevent them from rolling on flat surfaces, increasing safety and organizing your space. The set includes 10 pairs of dumbbells ranging from 2.5 to 25 kg, with chrome-plated knurled grips, stored in a sturdy steel rack, optimizing space and accessibility.
