So, you do 3 heavy sets, and then you do 7 sets with the same weight for 8-12 reps and rest 30 seconds between sets?
Not as such, TJTJ has given the links that should explain it.
But you'd do a total of 4 exercises take chest for example
Incline dumbbell bench 4 sets x 8-12
hammer strength press 3 sets 8-12
incline flyes 3 sets x8-12
crossover 7 sets 15 reps
only a rough guide. never hit the right notes with me so kind of ignored it
