Just got back from the States and these little fitness gadgets are appearing a lot on TV commercials.

It’s mostly aimed at women and it’s like one of those light-weight chrome dumbells only the hand grip and the ends are independent and you can shake the ends back and forth on an internal spring.

They’re specifically aimed at toning and shaping your upper body, arms and chest area, and the workout acheived is 300% more than with the same weight dumbell.

Shake Weights also come with a DVD with demonstrations of all the exercises you can do with them.
