Not real familiar with it, but I did think that I had noticed on a commercial usage of words such as "easy". In general, easy does not produce results. Now granted it could have ergonomic advantages to reduce injuries or repetitive discomfort, but for the most part results will come from the difficulty of the exercise. Some people often reply to such logic with statements like "yeah but this is something I would do" and my typical reply is something like "yes you may indeed sustain it longer than the more difficult devices but you would not endure long enough to get any worthwhile results and it would become another dust collector/coat rack".
