upper body from the front good shape , classic look
Still some to come off low back and around 10lbs should do it
I know your legs have been a problem, maybe a different approach to training my yield some results after 50
I dont push poundages anymore, lighter weights, slow and deliberate movements with full isometric tension throughout every rep, I also flex my quads between sets and old the contraction.
Then staright back on the set
Try machines rather than free squats , you can get better isolation on the quads whe you are not tottering around trying to focus on balancing a weight
Anything else I can do to help just ask.
