Some good advice in the posts above.
Injuries suck and you need to work with them in your training. I have herniated my L5-S1 twice within a year apart. NOT FUN
You need to work your core like a bastard and reprogram your body.
Examples - I used to squat on my heels, I now squat with the middle of my foot, which changes my motor recruitment pattern (which muscles activate first).
I do core work like dead bug, super man, plank, side plank EVERY DAY. If I slack off my back starts to hurt again. I now do core work first in my workout instead of last.
I can not (at this moment, but progressing) deadlift from the floor, it compromises my back. I now deadlift of the first pin my power rack and change my form to a more "squat" style of deadlifting.
Also as mentioned above;to do glute work.
Realize it may be a long road or depending on your injury you may have to change things like I did in your exercises and workout program.
Good luck brother
