Workout routine change

[ran365]

Hello

First post here.
I am 32 and working out for 17 years now, with many injuries during the years, mostly because of bad form.
I read about this program idea:

Monday

Squats (3 sets of 5 reps)

Bench Press (3 sets of 5 reps)

Chin Ups (3 sets of 5 reps)

Wednesday

Squats (3 sets of 5 reps)

Shoulder Press (3 sets of 5 reps)

Deadlift (3 sets of 5 reps)

Friday

Squats (3 sets of 5 reps)

Bench Press (3 sets of 5 reps)

Pull Ups (3 sets of 5 reps)

What do you think?
It is totally different from my regular routine that focus on isolating exercises.

Thank you

Drop squats on Wednesday, and add some kind a row (barbell rows are inferior to chest supported rows and cable rows, btw)

And any BW pull should be done to failure IMO

Do all that and you basically have Greyskull LP

Thank you.
What do you think about this reps and sets number?
Do you think it is good for gains?
And about getting to failure in every set, isn't it a way to getting injury?
