Apparently the technology of the design means that it creates 240 muscle contractions per minute and is 300 per cent more effective than traditional weights. Whether this is true or not, few of us have traditional weights to hand so anything that helps us exercise more is a bonus.
So how does the Shake Weight shape up? Well exercise alone won't achieve the body beautiful. You have to combine this with a healthy eating programme. If you can't get to a gym why not try it? Whatever its detractors say, Dr Lee Berk, Californian scientist, has released his research showing that the effects of laughter mirrored those of repetitive exercise. So if using the Shake Weight makes you laugh - double benefits!
The Shake Weight comes with a DVD to demonstrate the most effective ways of using it to exercise.
