Love the push/pull/legs split it's a classic.
I used to do -
Day 1: AM: Push, PM: Pull.
Day 2: Legs
Day 3: Rest / Cardio
Repeat.
Considering doing this again with all the covid stuff going on and my home gym is well setup. Caveat is I'm 7 years older than the last time I did it... RIP to my joints if I screw it up.
