The CTIA GROUP LTD Tungsten alloy fitness ball is a fitness device made from high-density tungsten alloy material, designed in a spherical shape, primarily used for hand strength training, grip exercises, stress relief, and functional fitness. This fitness ball combines the portability of traditional fitness balls with the high density and strength of tungsten alloy, making it suitable for fitness enthusiasts, athletes, and specific groups needing enhanced hand strength who seek efficient and precise training.

Tungsten alloy is a material with tungsten as the main component (85%-95%), blended with small amounts of nickel, iron, or other metals to improve processability. Its key physical properties include: high density (17-18.5 g/cm3), small volume, high strength and hardness, and environmental safety.

The tungsten alloy fitness ball has wide applications across fitness and rehabilitation fields. In fitness training, holding or rotating the ball effectively exercises the muscle groups of the hands, wrists, and forearms (such as flexors and extensors), which is particularly important for sports requiring strong grip strength like rock climbing, weightlifting, and tennis; small tungsten alloy balls are ideal for rolling between fingers, enhancing finger coordination and flexibility, favored by musicians (e.g., guitarists, pianists) or professions requiring fine movements (e.g., surgeons); additionally, it can serve as a weight for dynamic training, such as adding resistance in yoga or Pilates to improve core strength and overall coordination. In rehabilitation, the tungsten alloy fitness ball provides moderate resistance for patients recovering from hand injuries or post-surgery (e.g., carpal tunnel syndrome, tendinitis recovery), aiding in the gradual restoration of muscle strength and joint flexibility, with a recommendation to start with lightweight versions and progressively increase intensity.
