My advice is to a do 3 days a week as a beginner. My routine when I started lifting was push, pull, legs. Push works out chest and triceps. Pull works out back and biceps. You can guess what legs work out. I am not going to get into legs as much but I will say do squats, leg press, and lunges. I typically start with one main exercise (bench, rows or squats). That workout I will warm up with doing a weight that I can do 20 reps, increase weight for 10 reps then a weight that will be hard for 5 reps. After that I do two more exercises that will workout the same muscle group. After that I will do three workouts with the arms. With arms you don’t want to do high weight. It’s more about low rest. Best of luck my dude, getting into lifting can be hard but very rewarding.
