Why are bodypart splits not considered a good workout?

[SouthsideCigar]

Just curious why BP splits are so frowned upon. There are still plenty of compound movements and I don't think it is considered over training, unless I am mistaken. For example, what is bad about this plan:

Mon: Chest - Flat BB 3 sets (10,8,6), Incline DB 3 sets (10,8,6), DB Flys 3 sets (10,10,10)
Tues: Back - Pullups 3 sets (10,10,10), Rack Pulls (10,8,6), Close Grip Pull Downs (10,8,6), Seated Rows (10,8,6)
Wed: Shoulders - Light Front Raises (for warmup) (10,10,10), Military Press (10,8,6), Hang Cleans (10,8,6), lateral raises (10,10,10)
Thurs: Arms - BB Curls (10,8,6), DB Curls (10, 8, 6), Dips (10,10,10), Seated overhead DB raises (10,8,6), Cable Pushdowns (10,10,10)
Fri: Legs - Front Squats (10,8,6), Leg Ext (10,8,6), Leg Curls (10,8,6), Donkey Calf Raises (10,10,10)

Just curious as to why this is not considered an OK training plan as opposed to a 3-day or 4-day push pull split

Just not enough training frequency, and perhaps too much training volume all at once on the trained "parts". Some folks swear by this type of training, others find they do better with more of a push-pull setup as you describe, or with a full-body workout.

I'm not a fan of bodypart training in particular while cutting. On a cut, you may do better to train heavy and short, with less volume, but more frequency, to remind the body to keep the muscle, rather than destroy your muscles without enough food to rebuild the damage.

On a surplus this may not be such a concern. And of course, on juice, all bets are off - you can get away with all kinds of different training paradigms and you'll still grow.

This help?
