You are definitely right on the money when you said to strengthen you abs. As a personal trainer, I eliminate a lot of my client's back pain by having them do core ab work. What is funny is that no one likes to work their abs, but is would solve most of the back problems. I am not saying that you won't hurt you back working EMS but your body might be a little more tolerant to injury. EMS is one of the toughest careers out there because of moving the constant dead weight (not dead people) with the drunks and heavier than normal patients and maneuvering through hallways etc. There are different ways of lifting to strengthen your back, just as there are different ways for sport specific athletes. Just something to think about. Keep up the good work out there, even though you are not always appreciated, you are always needed.
