a) Full range of Flexion (closing)
Motion:
Most grip strengtheners, because they are being actively held
in place by the hand, are already partly through the flexion motion before the
exercise is started. When the hand is squeezed, only the final range of
the flexion motion of the hand is used. This would compare to doing a
biceps curl through the final half of the curl only. It is not an anatomically
accurate exercise.
When only part of the range of motion of the joint is
exercised, the muscles and tendons of that joint will becomes shortened.
Also, the joint surfaces won't get complete blood flow throughout.
Therefore, the cartilaginous surface and the ligaments of the joint do not get nutrients
throughout. Thus, the complete joint's surfaces and tissues cannot stay
optimally healthy.
The GripSaver Plus allows the hand to move through a full,
natural range of motion.
b) Full range of Extension (opening) Motion:
Try to find an exercise product that exercises the muscles
that open and spread the fingers and the hand. They are almost
non-existent. The few we have seen do not resist the opening of the
fingers through a full, natural range of motion. Extension is CRITICAL
because we have over-developed flexor muscles. This kind of imbalance is
the root cause of many climbing injuries.
The GripSaver Plus resists the extensor and abductor
muscles of the fingers through a full, natural range of motion.
