Every rep starts with the hands. Whether you're lifting heavy, dominating racket sports, or training for explosive contact, your grip decides your power. The NIVIA Xtreme Power Hand Grip is built for athletes who demand more—more resistance, more control, more strength. Its reinforced carbon-steel spring delivers adjustable tension from 5 kg to a massive 165 kg, allowing you to scale from warm-ups to advanced forearm training seamlessly. The nylon frame stays solid under pressure, while the TPR anti-slip grip locks your hold even when the intensity rises. For fighters, lifters, racquet players, and anyone chasing a stronger forearm engine—this is your daily power tool.
