Start doing TBT training 3x a week for 4-6 weeks as a starter, to get used to the biomechanics of weightlifting.
After that you have options.
2. A 4 day split, 2x Upper body, 2x lower body workouts, with a the 5 day format of UB, LB, Day off, UB, LB, Day off, Day off.

Some people will favour specific systems, others will do what feels best for them. Time and experience will teach you.
There's a few things to know regards any system.
1. Use good technique. Don't increase weight until technique is good and don't use something like the Weider Half reps method, where you do half a range of motion with more weight added. That's not very productive and may cause developmental problems.
2. Don't use more weight than you can handle. If you're not sure what you should use, be conservative, don't overestimate. It's easy to increase a low weight level, but too much may cause injuries.
3. Don't do things like Wrist Curls and Behind the Neck exercises, that cause risk to Bones and conenctive tissues.
That's for the future though.
