I always wonder about those products that are sold on infomercials in the wee hours of the morning. One that recently caught my eye is the Shake Weight. Actually, I was intrigued after SNL spoofed the infomercial (google that one, it is funny). It looks like a normal hand weight…but when shake it it does much more. The shaking is supposed to use dynamic inertia (whatever that is) to tone and sculpt your arms. I have read many reviews on this product and they are mostly positive. Self Magazine claimed that it would firm up your arms by only using it 6 minutes a day! It does look fun to use…but I have not tried it myself. Has anyone tried the Shake Weight? You can purchase it from the infomercial site or go to Dicks Sporting Goods to pick one up. I would recommend Dick’s…because you can return it if you don’t like it – plus, no shipping charges.
