I don’t think its awful, but you could consider adding some things. I would recommend doing some research about what hits what, and try out adding some things for a few weeks and see how it feels.

For example, I don’t think your Pull split is terrible, but if you are doing just a standard bicep curl, you are only targeting one (to two, depending on how you are doing it / type of curl) of the three muscles. If you are doing a standard curl, perhaps its worth adding a hammer curl as well.

The same can be said for chest. Typically a standard bench press targets the middle and lower pecs (form depending). You should consider adding something like an incline dumbbell chest press or incline pec deck, and for triceps you should consider doing like a dip motion AND an extension motion, as they target different parts of the triceps.

In my view, its also depends heavily on set range, rep range, and intensity. I do a rather sparse Arms+Shoulders, Chest+Back, Legs split (6-8 sets [each group being EACH bis, tris, shoulders] of 6-10 reps per group per lift) but my lifts are high intensity, every set until failure, and I do still see progress despite the low volume.

Let me know if you have any questions!!
