I do an upper lower alternating days routine. usually 4-5 days a week.
I pick 3 compound exercises and 2-3 isolation exercises with building muscle as the main goal and strength as number 2. i pick 2-3 exercises i want to improve the most and make them 3-5x3 with a 5rm with the goal of adding 5 pounds to that lift each week. If i ever don't make progress on any lift then i switch it up with a new lift or a different grip or stance. I never purposely go to failure always 1-2 reps shy of muscular failure. I always try to set a PR(personal record on each lift every week) A pr could be 1 more rep or added weight or shorter rest between sets or more sets or more total reps or the speed and form of a lift. I wear a belt on squats and deadlifts.

I took the deadlifts out since alot of people cant make progress deadlifting twice a week.
Sunday-off
I find this works extremely well for me and when im not cutting i can work out 5 days a week, deadlift twice a week, and clean heavy twice a week.
