Shake weight

The latest device to make its way across the pond has caused somewhat of a stir thanks to the slightly suggestive motion required to activate the toning properties, as commented on by American talk show host Ellen DeGeneres .

The basic principle is that the modified vibrating dumbbell strengthens and tones arms thanks to a technology called 'dynamic inertia'.

Its makers claim that six minutes a day of the somewhat comical back and  forth movement will tone upper biceps, triceps and shoulders.
