Id experiment with form and see what feels right. Try to keep the back fairly straight and look up to the ceiling. Some rounding of the back works better for some people. Depends on your body structure, arm length, etc. I would just get into deadlifting and see what you can do. Maybe ask some knowledgable lifters about form to get a general idea. Or even better, do some research on here. I learned alot from the members here on improving my form. The best way to get used to deadlifting is by doing it. It felt awkward for me when I first deadlifted, but I got 300 the first time I tried it at 19. I didnt do it for years after that. After a while it became less awkward. Now its my favorite exercise. Squats I still havent gotten the form on yet, but I almost never do them. PM me with any questions. Best of luck!!
