The Shake Weight Dumbbell looks ridiculous. There is really no way around that.

If you've ever seen the infomercial you probably had the same reaction I did. You laugh a little, maybe cringe a little, and then wonder if anyone actually buys this thing.

But the ads kept showing up for years, which made me curious. Products that stick around usually do so for a reason.

So I started digging into whether the Shake Weight actually works. What I found was more interesting than I expected, and honestly a little suprisingly reasonable.
