Medicine balls are effective tools to use to push your body harder and tone your muscles. Regular medicine balls are not weight-adjustable. The Stratos is different. It saves you space and offers 3 weight settings: 4, 6, and 8 kilograms. You can select the appropriate weight by turning the knob, pulling the lock, and removing Stratos from the stand.
