Unlike elastic-based exercisers that increase in resistance the further the unit is extended, 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.
