Dan John's Easy Strength, that he originally developed with Pavel Tsatsouline whose Greasing the Groove was also mentioned in the comments, follows a similar idea. It consists of workouts done 5 times a week, and lasting no longer than 15 minutes (for me, in practice, ~20 minutes was closer to the truth). The basic idea is to do 2 sets of 5 in push/pull/hinge/squat followed by a loaded carry at loads that feel almost too easy, 5 times a week, for 40 total workouts. There is some detail/progression added in his texts, but the basic idea is short, frequent, repeatable workouts that seem to lead to pretty good strength gains when run once or twice. He does say that you might want to do more volume-intensive program before/after, as everything tends to work for some time but not forever.
