I'm doing a full body routine right now.

I do it 2-3 days a week.

U start of 8-12 reps x3 sets and keep adding sets and Lower reps to be at 6x6 in a few months.

Squats
Bench press
Standing press
Bent over row
Lat pull downs
Seated bicep DB curl

It's an ass kicker of a routine that's 70+ years old.
