I've heard of that but don't know of anyone personally who has tried it. I myself follow Jim Stoppani Ph.D which has me committing for 12 weeks at a time. It is split up into 3 'Phases' of 4 weeks each, each week having 4 workouts (I do 5)

Each week within phase 1 has a different rep range than the following week.

Week 1 is 12-15 reps
Week 2 is 9-11 reps
Week 3 is 6-8
Week 4 is 3-5

Each lowering of the rep range subsequently requires you to raise the amount of weight you throw on the bar.

Then phase 2 comes and you repeat the same thing except with different exercises.

I don't see that training regime being too useful as it doesn't focus on any one specific type of muscle fibre causing muscular breakdown to be less than it would otherwise be.

I could be totally off here though.
