My deadlift has always been my best lift. At my best I was 6'1", 172, and could pull 455 twice while maintaining a 18 minute 3 mile (military stuff). I have normal length arms, a short torso, and long ass legs.
Anyway... I've always preformed this lift with 'strict' form. IE very neutral back position, and consequently my hips have always been a little higher in this movement which would always wreck my back when I start to get heavy. Anyway, I haven't done this lift for about a year and just started to get back into it about 6 weeks ago. I was worked up to 315 for a set of 4 and as usual my back started to hurt. I tried to get my hips to drop slightly and my back rounded a little bit. I said fuck it and pulled it anyway. It stretched my back a bit and I feel GREAT. In fact, I can lift better and more comfortably with a slightly rounded back. It's been 2 days and my back feels fantastic. I've been doing some research on this for the first time and i'm wondering if anybody else has any experience on this. I'm a little worried about messing my back up deadlifting like that, but in all honesty the whole lift feels much more comfortable doing it this way. Can anybody school me on this?
