@chris1975 I tried both a lot of variety and repeating the same exercises every day. Both failed for me. Repeating the same exercises every day led to elbow/shoulder pain. Having a lot of variety led to loss of motivation as there were always something I didn't feel like doing which killed my motivation for everything else.
I have been doing a 3 day split with little variety for a while now, but I am doing consistent progress and enjoy every exercise in it which makes it very easy to sustain over time and I haven't felt pain in months.
Day A: 6x superset Weighted pull-ups into bodyweight chin-up
Day B: 6x superset Weighted ring dips into ring pppu
Day C: 6x superset HSPU into lateral raises with dumbells
15-30 minute pauses between supersets, no pause between exercises in the same superset
60 minutes low impact cardio every day.
I also sprinkle whatever skill I feel like doing that day if any.
I got ring/bar muscle-ups, rto dips, FL/BL, HSPU, atg pistol squat.. basically most basic skills out of it. I am sure it's not optimal, but I progress, I don't get hurt and I have fun.
TL
R don't overthink things.. try something out, if it works for you keep it up, if it doesn't feel right or fun, change it up.
