Alex Gerrard is a fan of the Shake Weight
Exercise of the week is a new weekly feature in which we will describe an exercise and explain exactly what benefits is has on your body.
We can all get stuck in a routine of doing particular exercises, so it's time to try something new.
Have a go of each of Exercise of the Week, for the whole week, to change your routine and work muscles that you may not have been before.
This week we take a look at an exercise in which you need a product for, the Shake Weight.
Alex Gerrard uses them and they were recently used on the E4 reality programme Made in Chelsea.
The dumbbell-shaped device is an arm strengthening and toning hand weight which you move back and forth.
Using it for just six minutes a day will tone the arms thanks to a technology called 'dynamic inertia'.
While it may sound like a contradiction, Shake Weight say dynamic inertia is a technology that 'ignites the muscles in your arm, shoulders and chest'.
The device comes with a free fitness and instruction DVD.
