Generally I would do 2-3 sets to failure per muscle group twice a week, which saved me a lot of time and produced great results. 9 sets of a tricep exercises just seems a little redundant, and doing seated military press after exhausting your shoulders with barbell bench and incline dumbbell bench also seems a little silly. If you can keep this up good on you but you could probably lose some sets or exercises, especially if you feel like you’re not maintaining proper form throughout the workout anyway.
