that' why you rest more.....
Exactly. Based on my own experience, HIT or modified HIT training is the better option for me. When I started back in the day, I went with the 12-16 sets for biceps etc. volume approach. However, I noticed my greatest growth spurts every time I dropped the volume and increased my rest.
Over the years I have modified the training as I've seen fit. At times, I have also incorporated the Lee Labrada-style slow cycling of rep ranges, but these days I go with 8-12 reps without any specific low/medium/high rep periods.
During this and the past week, my chest and back got maybe four sets to failure, legs (quads and hams) a total of six, triceps and biceps two each, and shoulders and calves get a few each. Always a good warm-up first pyramiding e.g. on the first chest exercise.
This is just my opinion and my approach, which has worked better for me.
