For hypertrophy, using sets of 4-8 reps per set and doing 2-3 hard work sets is best. And if you’re ramping up it could be 2 slightly lighter preparation sets and then 2-3 challenging work sets. Four work sets can work very well too.
As far as weekly volume per muscle group is concerned, Brad Shoenfeld has presented data showing that doing 10 sets or more per muscle group a week leads to more muscle growth (+9.8%) than doing 5-9 sets per week (+6.6%) or less than 5 (+5.4%).
A safe assumption is that for maximum hypertrophy 10-15 sets per muscle per week is optimal. This would mean doing 4 or 5 exercises per muscle group for 2-3 work sets. More than that could end up being detrimental to gains.
**The weekly volume can be spread over 1, 2, or 3 weekly sessions. You can either disperse the volume equally, or do more volume for a muscle one day and less another."
You see where he wrote one weekly session? And everything he outlined is typical bodybuilding training.
