10 kg Dumbell

Once upon a time, in a small town nestled in the mountains, there was a young man named Jack who had a passion for fitness. He spent most of his days training with various weights and machines, always striving to push himself to the limit. One day, while browsing through a local fitness store, he came across a set of dumbbells that caught his eye. Among them was a 10 kg dumbbell that seemed to call out to him.
