Challenge each finger individually.
Exercise each finger with a spring-loaded button. Stronger digits cannot compensate for weaker digits. Five graded resistances are ideal for evaluating and charting progress. Includes an informative pamphlet illustrating a variety of finger exercises. A space-saving, plastic display rack with a set of all five Digi-Flex® exercisers is sold separately.
Five color-coded resistances are available:
Yellow: 1.5 lbs. (0.7kg)
Red: 3.0 lbs. (1.4kg)
Green: 5.0 lbs. (2.3kg)
Blue: 7.0 lbs. (3.2kg)
Black: 9.0 lbs. (4.1kg)
