Does Shake Weight Really Work?

Shake Weight claims to be the answer to people who are bothered by having flabby arms and fleshy shoulders. With Shake Weight your arms will be toned and your shoulders sculpted. They will be shaped and tightened at the same time, just by holding onto the Shake Weight. The foundation behind the Shake Weight is something that they term as Dynamic Inertia. Dynamic, because the Shake Weight produces a unique shaking motion that is dynamic, and inertia in that one needs simply to hold on. The Shake Weight promises to be more effective than regular dumbbells in this way, because the entire upper part of the body is put to work at a rapid pace just by holding onto the Shake Weight. The muscles of the arms, shoulders and chest are activated and with just six minutes a day, you will see the difference, they claim.
