Lifting with long-term lower back injury?
42 M, 285 lbs/6'9". I've been losing weight through calorie counting since last September, down from 340, and I want to start lifting to preserve/build muscle. Started attending the gym regularly just last week. However, I hurt my lower back pretty badly last May. I have recovered to the point that I am normally not in pain, but I have to be very cautious when bending at the waist while picking things up and working, or it can feel like being hit with a cattle prod.
Are there some best practices I should follow as I start lifting? Maybe some alternatives or modifications I could try for moves like deadlifts? I want to get stronger but I am feeling pretty nervous.
I saw it advised to try using a leg press machine, but the ones I have access to max out at 350, and that's only a little more than my body weight.
