Data Base - Fitness Program Software

I'm looking for database software to be able to pull equations form a database and insert them into a excel or like spreadsheet. When I set up a fitness program for a clients I plug equations into excel to that calculate percent of a maximum repetitions for each exercise in the workout. The equations as based of percentages for various goals so I have a large amount of various programs all with different patterns to the equations. I would like a program that can do this for me and insert it into a spreadsheet or a printable form that I can then use for my clients. If possible I would like the software to be installed on to various pcs as a standalone or requiring a standard database and spreadsheet software.
