ZIVA® Performance Resistance Bands are incredibly versatile, compact pieces of equipment with which trainers and users can prehab, rehab, warm up, stretch, and even undertake serious, strenuous workouts. Made with high-durability, high-elasticity thermoplastic rubber that can simulate multiple levels of resistance, these bands are easily integrated as strength and endurance tools into group class settings, but also work great as stretch-assistance tools when training alone.
