I have purchased a few different pieces of exercise equipment now and then when I see them on television. The shake weight mentioned in another post was one of them. Most of the time these things are absolutely pointless, but if they don't work for me they make nice gifts for other people. Sure, they probably won't use them either but it's the thought that counts, right? Well, the thought of giving... not the thought that I gave a pointless gift to someone when I did not want it myself. I have purchased a few simple items that worked, but those were mostly just over-hyped free weights or the occasional elliptical machine.
