How do you determine what weight to start at for the three sets of 5 (last one to F). Seeing if I understand this method: so you only increase weight if you get 8 reps on the last set? (e.g. 185x5, 185x5, 185x8) How often would you do benches? Any advice on an overall, whole body routine that is 2 or 3x per week in the gym.
