Client was told some BS in terms of pain

Hi BBM. Thanks for you all making this world better.
My new client is really anxious about his NSLPB, especially that the resistance training will cost his health in the long-run. He constantly repeats, that his disc protrusions will get worse if I load his spine vertically. I listened to him carefully and tried to open his mind.
Should I convince him and make him more using his back? Should I change exercise selection?
We doing something like this: 4x per week
Leg extension(cause he was afraid to squat with even his bw): 3x15@8
pressing machine(chest): 3x8-10@8
dense work in his abs and upper back

leg curls: 3x20
bench incline: 3x8@8
dense work(he says that he really enjoying it, so I keep it up)

hack squats: 3x6-8@7
feet up bench: 3x10@8
back again

lunges: 3x20(10 per leg)@8
db bench: 3x15
back and abs

We do LISS and HIIT.
He is goal is to lose fat, so I working with his nutrition (with Jordan’s guiltiness from\the tubes). He said that I should ask a doctor to find out if he can lift\load his spine vertically and to live a healthy and happy life?
I will repeat my question to be clear: how should I convince him? Should I even try? If he feels something in his back and will panic thinking that he’ll dead what should I do? Maybe I should modify some exercises, maybe change them?

P.S From the next week, I will try to work on his work capacity!

Belief change and behavior change are hard. These can be very challenging conversations it sounds like you are not adequately prepared to have, and it sounds like he is seeking out reassurance from someone in a “higher” degree of perceived authority on the matter. We can’t adequately prepare you to have this conversation in a brief forum post – it can take years to develop confidence and expertise in these sorts of conversations – but we do think that he should resistance train for all the reasons we have laid out in our content elsewhere. If he is unwilling to change his mind based on your advice alone (or if you feel you do not have the knowledge / skills / strategies to guide him through this process), I would recommend he pursue a 1-time consult with one of our rehab clinicians for initial education on this stuff.

Thanks Austin, I will give him a link!
