not a bad routine. but let me give my 2 cents. your basically doing a one body part per week bro split.
this traditional one body part per week bro split is NOT always ideal for your average lifters . your really cutting yourself short and missing out on a lot of potential gains.
""yeah but don't the pros do one body part per week splits like this, and look at them"".
the reason a lot of bigger guys will only do one body part per week is because they cause so much homeostatic stress on the one muscle group that they need a whole week to recover . you on the other hand likely do not.
heres an example-
pro chest day - he benches 495 for reps, he incline presses 180 pound dumbbells for reps
your chest day - you bench 185 for reps, you incline press 50 pound dumbbells for reps
now tell me who has done so much homeostatic damage to the chest and the CNS that you need a whole week to recover from it. obviously the pro. he's done 100x more volume. you on the other hand have done so little volume that your chest will recover in just a few days and will be ready to be trained again. by waiting so long to train it after its already recovered is just missing out on more potential growth.
I highly advise you try a training split where you hit multiple body parts per workout so that each body part is hit 2-3 times per week rather then just once per week.
having said all that, there are a few guys that even though they aren't that strong or cause that much stress, they still respond fairly well to one body part per week splits. BUT, a majority of my clients have gotten the best results by hitting body parts with more frequency
