Splitting muscles parts is the best way, beginner or not, to gain strength.
I will try to make it simple.
For example you could :
Monday
Front Squat
Work up to a 3-12 heavy ass set. (Could look like 45x20 135x6 185x6 225x6 275x6 315x9PR get it ? not too much volume but a bust ass set where you MUST beat a PR)
Leg Press
More volume but still go quite heavy. (Ex. 3ppsx12 4ppsx12 5ppsx12 6ppsx12 7ppsx12 9ppsx12PR More volume overall, last set was not failure but still quite heavy.)
Leg Extension
Light More volume focus really on contraction. 3-4 sets of 12+ reps no failure for sure.
Tuesday
Bench Press
Work up to a 3-12 heavy set.
Incline Dumbells Press

Get stronger and stronger, eat more and more and progress.
You could also move triceps from sun to wed with bi’s and back from sun to tue with chest. If you want sun off to be 100% fresh for quads. You could also add direct traps and calves work.
Start with this and make adjustment as you progress and see if there’s weakness. You could for example if your back is lacking add a second back training per week, etc.
If you feel 100% recovered and feel like you can handle more, go for it you can add another exercises per bodypart. Train and see.
The Split I made above is just an example, go with your needs. Ask the big guys here, progress and make us proud.
As far as diet goes, go simple. 2g per lbs of proteins, liquid carbs/protein post-workout, carbs+prot in the first 2 meals and the rest fats+prot. Send a PM to MightyStu if you really need help about it. At 6’0 170 pounds you really need some steak.
Keep us post, maybe open up a training log or send H4M a PM so he can make you enter the Brotherhood of Iron group.
