Description
Grip it. Work it. The TRX Duraballistic Sand Disc has handy grips around the entire rim for better control. Use them just as you would a medicine ball, except now you can stack multiple for an extra challenge (and easily stack them when not in use). This weighted disc is the toughest and only reinforced disc on the market, and lets you break a sweat with every move in a size that fits easily in a travel bag. Filled with soft steel sand to maintain its shape and reduce shifting.
- High-density foam rim maintains its shape
- Raised edges for better grip and control
- Soft outer won’t damage floors
- Stackable design takes up less space
- Steel sand filling
- Kevlar® fibers are approximately 5% of the material blend
