Welcome. Have you had a consultation with a certified SS coach? I'd sure do that before I make a decision about the lifts given your history. Are your diagnoses from your Doctor or are these self diagnoses? Cleans can be tricky at your age. Sully has a few in their sixties who can do them but I cannot. Are you still doing 5 X 3s for the DL? 5 X 1 is indicated for that lift. Do you have the book(s)?
