I hope this doesn't come along as too rude, because it's meant as honest advice.
- You're not a personal coach, physical therapist or something similar.
- You have not undergone any kind of certification (like SFG, SFL or similar certs from other institutions).
- From what I read in your posts you didn't even attend a course about training (like the SF 1-day courses, the Starting Strength seminar. etc.).
- You're 51, which means (ideally) you had ~35 years to train and say that you are already training with barbells (bench press etc.), yet you struggle to press the 24Kg and call it "heavy" and "Monster" in other threads.
At this stage of your journey to strength, fitness and health you have absolutely no business in designing any kind of routine or program.
You simply have to follow the proven routines from people who actually are in the position to design routines -> people who are coaches or PTs, people who underwent certifications or at least people who walked the walk for a couple of years and reached respectable numbers by doing a couple of different existing routines as written!
