Those might help.
Just do what you said, P/P/L or whatever works. Could look like:
Push: DB bench (incline, flat, decline, floor), flyes, DB press, lateral raises, tricep movements
Pull: DB rows, rear delt raises, rear delt rows, shrugs, curls
Legs: goblet squats, lunges, RDL’s, calf raises, farmers walk, hip thrusts
All the same movements you could do with barbells (or machines), just done with dumbbells. Don’t worry too much about it.
Good luck with your government’s rules. I’m in America but the corona virus just reached my state yesterday. We were one of the last ones! There’s another Italian poster on here, @samul, who will be dealing with the same restrictions as you.
