Automated workout/program creator (Excel)

I am a personal trainer who always has to repeat the same process of typing certain exercises or assigning certain stretches to clients. I believe that making an excel sheet where I make certain inputs (goal, equipment, contradictions, weight etc) and it automatically provides the exercises (stretches) best suitable for the clients workout regimen would save me lots of time in programming and would allow me to focus more on the clients themselves. Would also give me more time to acquire more clients. I have the exercises needed and the input ideas there but I would like someone who fully understands excel to help me put this idea together.
