I also like this split but do it a little different.
Day 1 chest, front & side delts, Tri
Day 2 back, traps, rear Delts, bi
Day 3 legs, lower back and abs.
Number of sets per day varies. 9-12 total on majors, 6-9 on minors. Never more than 30 in a day seems to be my limit. I keep busy between sets with 1 min if some cardio movements.
Some times I go 3 on 1 of or like above I rest when my body calls got it. On cycle it never calls for anything but food but I do rest also once or twice every week or so.
Cardio is done 2x20 min a week Hiit and 2x40 steady state. Depends where I am at.
This is a great middle of the road work split for bulking, shredding, losing weight or maint but can be taxing for some. It all comes down to your diet abc ability to recover.
