A Squeezerciser is a palm sized finger, hand and forearm resistive trainer, which looks like a vibrantly-coloured very squeezable sponge Smartie.
Excellent used therapeutically for strengthening weakened or injured muscles and joints, as well as training healthy hands of all ages.
Particularly useful for sports where hand strength figures highly, and for musicians.
And a Squeezerciser is a very, very good stress reliever.
Consider placing one on your desk, slightly north east of your computer.
Maybe next to your mobile phone.
