How does this training routine sound?

[Dream2BShredded]

I'm currently doing a PPL split so training each muscle group twice a week. However, I was thinking of trying the following:

Day 1: Chest and triceps
Day 2: Back and biceps
Day 3: Shoulders and abs
Day 4: Legs
Day 5: Rest

Would this type of training be common? I currently do chest and shoulders together, however I'd like to give shoulders their own day separately due to energy levels decreasing after smashing my chest. I enjoy being in the gym so the extra day doesn't bother me. Issue is that if I do this, I won't be working each muscle group twice a every 7 days but rather each muscle group twice every 9 days now. For example, I'll be going from having a 4 day rest between muscle groups to a 5 day rest. Will that make much of a difference or am I completely overthinking this?

Thanks!

Can't really give an opinion without knowing your program, before and after. You've only given a schedule and body parts.

Split really doesn't matter.

What you put into each day matters

The split looks Good, no overlapping of secondary muscles being worked day after day

There is 7 days in the week, not 5. That isn’t a program, or even a list of exercises. If I had 5 days to work out though, in a gym, my general layout would look something like this:

Day 1: Chest and shoulders
Day 2: Legs and abs, light lat and upper back work
Day 3: Rest
Day 4: Back with light shoulder and chest work
Day 5: Arms with light leg work
Day 6 and 7 I would rest completely, probably have a cheat meal in there too

OP, as Wolf said the routine is less important than the degree of well-directed effort within each day. As you gain experience, you'll figure out how to cover all of the important bases via different methods and find that you can vary your routine significantly, and that it is fun to do so.
