Want to exercise on the move? This set of dumbbells and suitcase will take you wherever you need to go. The black case is designed with sturdy plastic and a padded insert inside to carry bars and weights safely. The dumbbells are disassembled, so they don't need much space to be transported. Before starting your workout, simply place the discs on the bars and start exercising in no time. Securing the weights with the star-shaped clamping screws is easy and safe. The kit includes 8 cast-iron weights (4 x 2.5 kg and 4 x 1.25 kg) for a total of 20 kg. With these weights, you can choose between one 17.5 kg dumbbell or two 10 kg dumbbells.
