Good Morning

Hi, Thats a good point you are making regarding the moment arm and the load on the back. It's just that my trainer has been prescribing me the goodmornings and RDLS for about 3 weeks now ever since I told him that I get low back aches after my long nusing shifts (my part time job). I can say, I've noticed the back pain is now actually almost non-existent. I used to do normal sumo and conventional deadlifts as prescribed by him before, but now we focus more on the good mornigs and RDLS. I can say, I'm not aiming to get back strength by doing good mornings, rather, back endurance and load like a baby in compaison to RDLS or proper deadlifts. With 20-30kg on my traps, I feel for a hamstring pull and not lower back pull, and go down to where I'm comfortable, which is a little less than perpendicular. I think good mornings actually are a functional exrcise for me. Yes they are pretty advance and I wouldn't reccommend them to a typical client, but for people who spend time bending a lot, such as riders, or especially people who bend with loads on their back, such as nurses, I think they can be useful. Please educate me if I am misunderstanding something.
