incline BB bench press - 3x8-12 (not sure what the numbers represent)
Wolf ment it like this: 3 sets with 8-12 reps. When you can do 3x12 set you increase weight. You go back to 8 rep standpoint. Once increasing weight you must be able to do atleast 3x8 or the weight is too high. Then you work towards 12 again, you achieve it you increase weight and go back to 8 reps.
1-3 rep max sets: <-- Increse explosive strength on timeframe of 2-5 seconds but not so high overall mass & strength or even endruance gains.
5x5 rep sets: <-- Increase muscle strength but less endurance (provide mainly .
3x8-12 rep sets: <-- increase muscle strength, endurance, size gains equally.
3x12-15 rep sets: <-- increase muscle endurance & size optimally, but minimal strength gains. (In some cases/some exercises not that much mass gain)
Eitherway, mixing 5x5 weeks and 3x8-12 weeks and couple light weight weeks with high rep range, with less weight is optimal for keeping body guessing after it starts getting used to similiar workouts.
