I just stumbled upon this article via Google search:
Its an old one of course, but I'm intrigued by the curl-grip deadlift and original good morning lifts as I don't recall ever seeing them before. Do you still see any use for these lifts?
I'm following your Power Look routine at the moment and thoroughly enjoying it so I'm in no hurry to incorporate either of them, but I do have quite a weak upper back and less than ideal posture, so the original good morning in particular looks interesting to try out somewhere down the line.
If you still view it as worthwhile, I'm guessing that either light weight for moderate reps as part of a warm up, or light to moderate with slightly higher reps at the end of a session would be the best use for it?
