Most grip tools only train closing strength, but this silicone finger exerciser gives you resisted extension—a crucial but often neglected movement for balanced hand, wrist, and forearm development. The open-web design means you can apply extension resistance from countless vectors — helping you build strength through the exact angles your sport, instrument, or daily life demands.
Perfect for athletes, climbers, lifters, martial artists, musicians, and rehab work, this tool isn’t just for injury recovery—it’s for creating a more capable, injury-resistant hand system.
Train extension from any angle – Sit, stand, or rotate the web to change vector direction and challenge your extensors in 3D space.
Comprehensive hand balance – Counters the overdevelopment of flexors from gripping-heavy activities, reducing injury risk.
Customizable resistance – Comes with two levels so you can progress over time or match resistance to the exercise vector.
High-quality silicone – Durable, grippy, and comfortable for extended sessions.
Ultra-portable – Toss in a gym bag, keep in your desk drawer, or use as a warm-up before climbing, lifting, or performing.
With its ability to load extension in nearly infinite directions, this is one of the most versatile and overlooked tools for truly complete hand and forearm strength.
