electronic ab machines....any results?
For the past few months I have been seeing infomercials on many new electronic ab stimulators. Ab Tronic, Ab Energizer, Rio Ab Belt, etc. Has anyone had any results with these machines? I believe that I am more interested in the Rio Ab Belt because I have heard better reviews on it. If anyone has purchased and/or used these machines, could you please post your opinions on them? Results, positives, negatives.
