Ok, here's the deal. I've been plagued by back injuries the past 7 months and haven't been able to deadlift over 300 since then. I strained a lat in June of '10 and wasn't able to lift because of football for the next 4 months. I fractured my L4-L5 in October of '10 and didn't deadlift at all for another 3 and a half months. My best deadlift before I got hurt was 350x1.
I'm currently running WS4SB and today was max effort lowerbody. So I decided to deadlift for the first time in 7 months. I mysteriously hit 335x4. I don't know what the hell happened, I would've guessed that I would've barely been able to do 225 after a 7 month layoff. I've been doing a shit-ton of abs, revers hypers and lower back since I was cleared to lift again back in December. Could anyone explain to me what happened?
