Product Description
A functional training essential, the ZIVA® Power Core Bag redefines strength, stability, AND functional training, offering unpredictable, full-body resistance that engages more stabilizer muscles than traditional weight lifting alone ever could. Designed for power, endurance, and versatility, this bag is built with heavy-duty nylon straps, a thick PVC skin, and large, easy-to-read weight markings—making it as durable as it is dynamic. Airhole endcaps allow for safe compression during intense movements, ensuring that this bag moves with you, not against you. And unlike traditional weights, the shifting load of plastic microbeads and a sand-filled liner bag create constant resistance variation, forcing muscles to adapt in real-time for enhanced coordination, strength, and control. Perfect for compound lifts, high-intensity circuits, and full-body supersets, the ZIVA Power Core Bag delivers instability, versatility, and power-building potential that traditional barbells simply can’t match.
