is very different from this ^.
Paul Carter and Wendler have some famous/infamous goals in their "What Constitutes Strong" rant, discussed here. Like squat or dead 500x20, press 315 overhead, do 10 pull-ups with 100 pounds added.
Dan John has some more reasonable (arguably more realistic) goals in this article. Bodyweight bench x15, double bodyweight deadlift for reps, 15 pull-ups, etc.
For the actual challenges, not goals, a while back I came up with the 365-rep New Year's Challenge. One upper body exercise and one lower body exercise, 180-185 reps each, done in any breakdown, making the whole workout 365 total reps.
