This sample gym workout routine is what I (GP) would describe as a beginner to intermediate strength program - this does not mean a beginner should attempt this gym workout routine! Simply, if you (or your client) has achieved reasonable progression with "less advanced" gym workout routines, such as the sample Toning for Men 12 week gym routine, then the sample strength program below is a sensible progression.

The sample gym workout can be found in the acclaimed book Gym Workouts: Maps to Success and the 5 star rated workout app GP Shuffle.
