In fact when i started training again after a 12 year break 2 years ago, one of the first things i was told by the token big eastern european dude in my local Next Generation was 'dont be doing Goodmornings, youll not be able to walk in 6 months if you do them'. Granted my form was probably bad but he didnt say 'your form is off' he plain told me that GMs would cripple me.
Being a born again noob, i listened to him, after all, he was a big guy (so i thought back then).. in hindsight, i now realise i never saw this guy do more than a 1/4 squat, never saw him deadlift and rarely saw him do more than various dumbell presses and curls. I was still in the stage where big chest, big shoulders and big biceps = big guy, that view has changed quite a bit now.
So when i actually started reading stuff by actual strength coaches and saw them not just advocating but demanding people do Goodmornings, i took a second look.
I have a bit of a back problem in that when it 'pumps up' it gets painful to walk, 1/2 a mile usually does it or most form of work that involves lower back. However in the 3 weeks ive been doing GMs again, my back hasnt nagged at me once, and ive thrown a fair bit of abuse at it, gone for walks of several miles and even chased a sandwich van up the street as i wanted a yorkie and he was driving away.. i didnt catch him, but the realisiation id run and my back was fine with it was better than the smooth chunky chocolate goodness.
So could it be that my eastern european friend had it all wrong, and in fact Goodmornings are the best thing you can do for a strong healthy back?
Im sure a lot of 'health professionals' would cringe at the idea of putting 100kg+ on your back then bending at the waist/hips... but all i know is my back has never felt better, and all evidence points to the mighty good morning as being my saviour.
