Xtensor XCB100 Xtensor Hand Exerciser for Strength
The Xtensor does for your hands what yoga does for posture: dynamically rebalancing strength in your hands, wrists and forearms deep into the elbows, the site of most elbow pain. Designed to perform in the exact opposite way of squeeze ball type devices. The Xtensor exercises your ?? as you open them, stretching and strengthening your hands in a completely different way.
