Assistance with situation and routine

Hi all, I'm relatively new to working out to a proper routine. Been doing body weight stuff and continuously refining my squat and dead lift technique. My question is this, my routine consists of a push/deadlift day on saturday and pull/squats day on monday. On thursdays i have a posture/pre-habilitation class which is quiet taxing. On this routine i am directly hitting each body part once a week. Im not trying to burst anyones bubble or anything I'm asking for some recommendation and guidance. Will hitting each bodypart once a week be optimal for my level of training experience? As the class on thursdays is taxing and becuase of this i am unable to train each group twice a week.

Push/deadlifts:
Deadlift 3 by 5
Dumbell shoulder press 3 by atm 9
Dips 3 by atm 7
Skull crushers 3 by 12

Pull/squats:
Squats 3 by atm 9
pull ups bodyweight 3 by atm 6
Inverted rows bodyweight 3 by atm 9
barbell curls 3 by atm 12

Cheers.

what do you do int he class?

Its exercises which assist with posture and movement efficiency. Most of them consist of isometric contraction over the course of an hour.

Why is there no bench? Dont like it or injury prevents it?

Shoulders and Delta begin to tighten and hurt (injury pain) from them

From all varieties of bench? Flat, incline, decline, neck press, wide grip, narrow grip, palms in? It surprises me that you can perform dips, but not bench. At least not dumbbell?

Keep doing what you are doing, ensure your nutrition is good and if you aren't getting the results you want after 6-12 weeks.. consider re-jigging the routine to fit in at least 3 weigh sessions across the week.

Thanks for the advice Judgey and Wingman. Yeh that is what I will do. If 3 weightlifting sessions a week is too much, I will just stay at two a week and do and do full body and see how I respond.
