If youre completely new to lifting I would reccomend something like starting strength.
Here is the The Original Starting Strength Novice Program, you alternate between A and B and rest every other day or after 2 days depending on how you feel. 3-4 sessions a week.
3x5 Bench Press
5x3 Power cleans
As you can see there is no "back day" or "leg day" but instead this program hits the entire body on all training days, this forces the whole body into growth and is much faster and more effective than a body part split for a beginner lifter.
Good luck and dont forget to eat alot.
