Smovey Power oscillating rings

either 4 or 6 steel balls. The innovative grip system allows the balls to move freely through the entire tube. By swinging the rings forwards, backwards or in a circle, you set the steel balls in motion. The rolling movements in the spiral hose generate a vibration that covers a broad frequency spectrum. As the oscillating rings move, the frequencies change continuously, which means that the nervous system is constantly confronted with new, unpredictable stimuli. The nerve tracts transmit the impulses to the brain, which can be felt as a gentle tingling sensation in the body. - Product details: - Material: polyvinyl chloride (PVC), acrylonitrile butadiene styrene (ABS) with steel balls - ø: 22 cm - Weight per ring (green): 0.5 kg - Weight per ring (black): 0.65 kg - Components: - 1 pair of vibrating rings - 1 training DVD - Experience reports (brochure) - Smovey Facts - Smovey Booklet Exercises: Proprioception, coordination, strength endurance - Product type: Fitness ring, weight rings - Training level: Fitness training.
