Ok, I have not done deadlifts in over a year, and so today, i throw on 160lbs, as a warmup. I do this because I know my legs are still strong, I have been keeping them up.. then.. as I am going up, my back curves in.. FUCK I could not keep form with only 160 lbs?!?! wtf is that shit? I had to lower the weight a lot just to be able to keep form. I wasn't expecting this to happen at all, infact I had never even thought of it before it happened. So basically, I need some back strengthening exercises, and I need to do them a lot, because I have basically one month to make some good improvements. I am also working on my upper body strength, but I can't do any real explosive exercises yet, so don't really worry about that, the main thing I need is exercises, stretches, and how to keep from getting too sore for my back. thanks.
