Meet IsoTone
Compact resistance.
Both directions working.
Hold one wooden handle in each hand. Squeeze against resistance, then actively expand against resistance. The return is not an idle phase—it is the second half of every cycle.

The IsoTone difference
One device.
Both phases of motion.
Strength is not only about heavier weight. It is also control: steady effort through the complete squeeze–expand cycle, without an idle return.
Expand strong
Pull the wooden handles apart deliberately, training the opposing muscle action.
Build a one-minute set
Aim toward 50 controlled cycles in about one minute as your technique improves.
Correct grip matters: hold one wooden handle in each hand. Keep fingers clear of the moving shaft and body.
Real IsoTone exerciseA simple place to begin
