Prohands is the original spring-loaded, finger-piston system. Prohands is used by professional athletes, world-class musicians, and as a rehabilitation tool. We offer various models/resistance levels so you can find the hand exerciser best for you.
Prohands hand & finger exercisers are made to strict manufacturing standards using only the higest-quality components -- ABS plastic, Stainless Steel Springs, and FDA-approved Santoprene.
Don't be fooled by cheap knock-offs made overseas, or models touting adjust-ability. The range of resistance in an "adjustable" model is grossly limited. Squeezing a ball or using one of those old-school v-grips is okay for gross grasping strength, but only Prohands isolates and challenges each finger individually for strength, dexterity, and endurance in the entire hand, wrist and forearm.
