What are peoples thoughts on the following kind of periodization for hypertrophy (not strength) gains -
Phase one - rep progression
start with 3x8 for an exercise, and progress until you can do 3x12 with the same load
Phase two - set progression
stick with sets of 12 reps with the same load but increase the number of sets you do each session until you are doing 9x12
Phase three - transition to load progression
increase the load a small amount each session for two sessions and reduce the reps by two for each session until back to 8 reps a set
Phase four - load progression, volume reduction
each session increase the load a small amount but drop a set.
When back to a tough 3x8, take a week off then start over.
