Anon, Have you tried the JP90 routine that MrHammer provided. It is a great routine and it has worked like a charm for my husband and most of your top gainers. It is a great routine and easy to do, just more time consuming but like with any exercise once you condition your unit, you then have to challenge it by increasing intensity(do not hurt it, just give it a more intense workout). My husband did the JP90 routine exclusively for 18 months because he had gains with it that entire time as shown by my signature. Whether the JP90 or another routine of the many shown in the sticky threads, just chose one to help you increase your level of intensity. Good Luck!
