I did try doing that many, many years ago. Gosh before I was 21 I bet I know it does add a few pounds. I was young then and didn't stick to it too much. Not sure if it's cause I didn't see results. I don't remember. HOWEVER, I do now have a $350 monstrous weight machine down in the basement that my husband HAD to have. He used it 1 month Maybe I should get some use out of it. It's a matter of know what to do thats tough. I'll have to look on line for some info.
