Well my first question is can you hurt your upper back doing Romanian Deadlifts, I had a compression break when I was 8 and since then hurt that spot a few times nothing that didnt go away in a week or so,(the break was in the upper back) this time it seems to be going away too but I just wanted to ask could it be that i hurt my back doing RDs.
The second question is since my back isnt healed yet I am replacing squats with weighted one legged squats, I was wondering if one replaced squats with one legged squats not for a while but for a long time mayeb for the rest of their life can the same benifits be achieved through one legged squats in terms of muscle gained and verticle explosivness gained?
