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.
The Stratos is made with foam, plastic, rubber, and steel. It measures 11.8” W x 13.75” H x 11.8” D. This cool product was invented by Peter Pelletier.
