Find an app that does this:
Main lift (main moving muscles legs/chest/back)
Supplemental lift for above
Accessory stuff for arms and core and anything you like to do.
Whether it is full body or upper/lower or push/pull/legs or even a bro split, that is all you need.
3-10 rep range depending on goals. Don’t get bogged down with bullshit like “optimal”. The best plan and/or app is the one you’ll use consistently.
