Yeah, exactly. Your basic scheme is “OK.” Full body, 3 days per week, 3-4 moves, about 20 lifts (average) per move, per day. That setup has been around for a long time.
But like you said, you need to find that “Sweet Spot” so you can recover and progress. Different guys have come up with all kinds of ways to personalize the basic full body plan. From simple to pretty complex. Your stuff doesn’t look much crazier than some of these.
