Lumbar disc herniation, which exercises can't be done in the gym?
Don't pull, squat, sit down and row. Can't do too much. Just say what you can do. Dumbbells, barbells can be lifted, bench presses should be ok, but you can control the weight, flat birds can, and butterflies can clip their chests. Remember that you can't do anything that requires bending hard. You are going to exercise, and you will get hurt if you are not careful.
