The simplest example I have of this is the program I made for my parents, ATG For Longevity, where you spend just 15 minutes a day on:
Thursday Lower Back
Friday Upper Back
Sunday Optional Elbows
In reviewing it, I realized it would also make a great formula for someone in-season, or someone who is new to my training and wants to slowly master the exercises without having to commit more than 15 minutes a day.
