I have always made progress in the deadlift but have recently lost over a third of my strength in this exersize.
For some background info, I took 2 weeks off of training at the end of a cycle. Usually I am stronger by the second week of my new cycle than I was at the end of my previous cycle. This time I am one rep stronger on all of my pushing movements and the same rep on all of my pulling movements except the deadlift, which is down 5 reps. My deadlift went from 265 x 12 at the end of my last cycle to 265 x 8 the first workout - then this morning 265 x 7. The weight felt like it was bolted down to the floor and I even stopped before the first rep to make sure I hadn't loaded the bar with too much weight.
To complicate this question, I decided to do a cutting cycle since I 've been bulking for about 6 months. I'm a naurally lean person and have never done a cutting cyle before but I lost my abs so I decided it was time to do one. My calories are about 600 less than before plus I added cardio for 20 minutes 3 times a week. Ironically my weight hasn't changed at all in the last two weeks of cutting.
Any ideas why my deadlift has severly weakened while all of my other lifts are the same or progressing? Why no weight loss?
