Unlike elastic-based exercises that increase in resistance the further the unit is extended, the Constant Force X-Tend uses retractable-based resistance, which keeps a constant level of resistance from start to finish. Ergonomic in design, the Constant Force X-Tend works the Intrinsic and Extrinsic Extensors of the hand and can isolate MP/PIP/DIP joint motion. It also allows each finger to exercise independently with smooth, consistent resistance, thus improving range of motion, endurance, strength and dexterity more effectively.

• Exercise each finger or thumb independently with smooth, consistent resistance to the Intrinsic and Extrinsic Extensor muscles throughout their full Range of Motion
• Improve range of motion, strength, dexterity, endurance, circulation for each finger as well as the hand, wrist and forearm.
• Ergonomic design fits comfortably in hand, and includes ability to isolate PIP & DIP joints
• Two hand straps provide comfort, stability and proper tension allowing fro advanced exercises with maximum improvement
