It all depends on the level of the person, usually in one session you shiuld have around 20-25 Sets !
always start ( after Warm up) with a principal exercise ( your main focus ) or technical excercise depends on your priorities . stay between 3-6 series . use complementary exercises at the end . If u can for example hold a tuck FL 6″ you can do 4-6 sets of 3-4″ .
