I had a spinal fusion about a year ago in my lower back due to a herniated disc and I'm just getting back into lifting. My back still bothers me on occassion, and as a result I can't do any squats, deadlifts, or anything bending forward with weight. I lost a lot of weight from not being able to lift for a while, and so I need a good bulking routine that doesn't incorporate movements that will hurt my back. I can either do a 3 or 4 day split but I need some help. Anyone have any ideas?
