The plastic dumbbell set allows you to use several gradations up to a total weight of 12.5 kg on one dumbbell or 10 kg each on both dumbbells. The weight plates are covered with plastic. This absorbs noise when laying down and protects sensitive floors from dents and scratches. And the star locks keep the weights securely on the barbell bar. In dumbbell training, most people first think of the classic biceps curls and triceps stretches. Basic exercises are also possible with the 20 kg plastic dumbbell set. For example, you can use the dumbbells as weights for shoulder presses, squats and lunges. And that's not all. An extremely effective full-body exercise with dumbbells, for example, is the so-called dumbbell thruster, a combination of squat and shoulder pressure.
