Any ideas on how to adopt training setup for different age groups in masters?

My idea was that 25-30 year olds should maybe not train in the same way as 40-45 or 65-70 ideally (if given same amount of available time for practice). Should you typically go down on yardage per day but keep number of days? Should you typically go down on yardage and increase weight lifting? etc etc Any input anyone? /Per
