Do the consensus of studies support optimal muscle hypertrophy to train each muscle group once or twice per week? Also, any consensus on how many days of weight lifting a week is optimal 3, 4, 6? I was reading Jim Stoppani recommends switching every 8 to 16 weeks between training each muscle group once a week to twice a week. This would seem to make sense in terms of supporting periodization and muscle confusion.
