How much do you squat? [1-3RM]
What are you training for/goals?
How long have you been training?
One one side: At least you train your legs. At least you choose squatting over less optimal lifts.
On the other: Your upper body day looks like shit. 3 open chain presses and one pull? Weak sauce. Also If you are a beginner trainee [ie. 1-2 serious years] then you will likely garner more benefit and balance from squats and other lifts. Things like deadlift, or at least good mornings, are great for beginners.
If I were your coach I would get you to do Squat [or variant] and 2 other leg based lifts on one leg day and Deadlift [or variant] and two other leg lifts on your second lower day. The other lifts would likely be unilateral lifts and explosive lifts [again, depending on goals].
In short: It is not optimal but I myself have done it and will do it again... When im on a diet or delaod. Not for regular training.
