A hand exerciser comprising a rigid elongated horizontal base whose undersurface is covered by a soft, corrugatued material. Across the top surface of the base are longitudinally affixed three support walls so as to define two equal exercise spaces between the support walls which are braced apart by abutting crossrods. Affixed to and rising above the support walls in similiar plane are four opposite side guide plates with aligned holes, slots, and notches through which a variety of various shapes and strengths of simultaneously and latitudinally strung reaches transverse for exercising against. Also, adjustable rods transverse for palm down bracing of the hands. Anchor and guide bolts secure and guide the reaches. One support wall additionally includes an overhang portion of a rigid material shaped so as to stagger the reaches and to which are affixed four modified guitar machine heads for tightening and lessening of reach tension. At the bottom of each exercise space are two raised platforms with slots therein into which removable rectangular tabs are inserted so as to define eight spaces between the rectangular tabs within which isometric abduction and adduction exercises are performed. Two of the raised platforms removable tabs are spaced to accommodate small to medium hands while the other two are for medium to large hands thus resulting in a device which can isolate all of the digit joints and provide flexion, extension, abduction or adduction exercises for strengthening all of the intrinsic and extrinsic muscles of the hand.
