I will assume that your goal is to build as much muscle as possible.
If you have been training for more than 2 months it may be time to do a few muscle groups per session. Back, Legs, Chest, Shoulders (and traps), and arms can be an option. Your muscle group must be "ready" in order to be trained. Sufficient rest must be taken care of between that muscle group, and/or indirect movers. If you want to train chest but your triceps are sore it wouldn't be the best idea, the same with back and biceps. Shoulders are very tricky because they interact in basically every upper body muscle.
My current split normally is right now:
Rest on weekends, I end up pretty much fried.
You see that after shoulders (where triceps play an important role), I train arms. I haven't had problems these weeks so I don't need to change it. This split works well FOR ME. Maybe your chest workout is too uncomfortable so you can't train back the day after, you have to train lower body. Maybe your triceps weren't really bothering you so arms next day is no big deal. Maybe your legs lack a lot of development so you wanna increase frequency and do them twice a week. You may train 7 days a week more than 1 time per day, you may be only training for 4 days in the week, it depends on YOU, you shouldn't fool yourself and be lazy though. Most people looking for serious progress will have to train a minimum of 5 days.
Focus on which muscle groups interact during any given training day, to have the clue of what you're gonna be training next day, or if you're taking a day off (in the split). I won't give that to you, because if after a few months you don't know that pulldowns are for lats and lateral raises are for delts it may be a better option to find a new hobby.
Most important, you need to start to listen to the feedback that your body gives you. If you're following program A but your tricep joints feel like shit, would you add more weight the next workout because the table says so? You need to learn that because nobody can notice better than you.
