There are a couple of superficial reasons. Firstly, my core was still fatigued from the work I did on weds. I thought I'd kept the volume low enough, but the unusual stimulus was more fatiguing that I'd planned for. I was also very tired, as I'd only remembered that the gym was closing at 12:00 as I was going to bed at around 2
But also, I've fallen victim to two other factors. 1) I have not been able to deadlift consistently for various reason for over a year, which means I've experienced "technique creep" and slowly lost some of the joocy corrections I made prior to injury. 2) Due to not working on it for 2 years, my lordosis has slowly returned. To be fair, it had basically completely gone when I stopped, but I now know that I need to revisit some of the mobility/exercises occasionally.
These two together have meant that I've developed a slight over extension moment in my lumbar. This is how I used to deadlift, and it basically meant that me psoas was hugely over recruited when I was trying to maintain a flat back (which was actually marginally over extended). This then becomes a battle of hip flexors (e.g. psoas) vs hip extensors (glutes, hams). Obviously extensors win, but at the expense of power and massive flexor fatigue.
This is all fixable, but probably not in 3 weeks.
Training 03/02/14
Not having the best run of training! Struck down by a very upset stomach that doesn't seem to be an actually illness.

Plan was for heavy doubles, but as I was ramping up the weights I felt closer and closer to a brown shorts catastrophe. Opted for some doubles, and felt a lot better by the 6th set. Essentially, this session has been switched with Friday.

140 was there for a no hand off PB, but I was running out of time and the doubles were more important
