I still pretty much follow a push/pull/legs split primarily built around freeweight exercises (with cables coming in a close 2nd...lever machines can GTFO haha). Very few isolation movements, though I'm starting to add certain ones in like shrugs depending on where I feel I'm lacking. Just about everything will be super-sets if there's a logical exercise to use as the super-set (examples being adding upright barbell rows or rear dumbbell flies to primary pull movements like seated row or bent over rows). Unfortunately I've more or less ditched deadlifts AGAIN thanks to lower back cramping every time no matter the weight, stance, or form...it just happens though squats are back on the board and going stronger than ever working weight isn't as high as I'd like, currently 130-140kg 5 sets of 6-8 reps, though I got myself a PB the other day - 150kg 3 reps absolutely ATG :D
I train most days if I can, sometimes twice (short lunchtimes session, then finish it off in the arvo). Only ever take "rest days" when I feel I need it, though I still don't really ever schedule them so to speak
