@sammyclifnote I'm all for full body and I'll outline my situation and why I think it's great:
I started with upper/lower split as a complete newbie, doing 4-5 days per week.
Now I'm doing full body 3 days a week and I feel like the cadence is helping me realize mo gains, progressive overload and just getting better at the exercises, while minimizing injury. I'm 40, so I prioritize recovery and injury prevention more than I may have when I was younger.
I generally need 50-60 min for full body and it could prob go a lot longer if I added a some more isolation exercises. You could also do 2 day split and 1 day full body -- maybe not hitting muscles with as much frequency, but still effective.
I'll vary the exercises by trying to choose 3 main exercises per category (Push, Pull, Press, Row, Squat, Hinge ) -- I also incorporate Curls sometimes and always do some shoulder isolation work (since they're weak as fuck), but I'm mainly focusing on compound movements, since I'd consider myself a novice still.
Squats, for example I'll do Lunges one day, Squats one day, and Bulgarian Split Squats, on the final day. Sometimes I double up only do two of those and sometimes I just do an exercise for one category for the week if I want to focus on that. There are some exercises that I always do like DB bench press, although sometimes I replace that with dips. Overall, I try to stay flexible on the exercises, but have some old standbys I always come back to. Sometimes I'll add in something exotic like the DB Pullover....
I don't know if that helps at all, but I'd definitely recommend the 3 day full body workout as pretty optimal for anyone who wants to build a solid base before advancing to more complex and hyper-focused workouts that intermediate lifters require for progression.
