So I got the 200 up to my knees and I was shaking, lost control and I failed the whole set.
I think everyone should take a minute of watching your porn/tv shows and read what I have to say.
It is important to understand that doing more squats/bench/deadlift does improve your squats/bench/deadlifts BUT only to a certain degree. This is where other accessory workouts are important eg; DB rows, BB rows etc etc.
Last week I got a 195kg x 5 RAW. I lift with straps most of the time unless I am attempting a true 1RM. There is an argument about pulling mixed grip all the time because you might experience some imbalance and might just affect the progression of your bench ( I wouldnt want to make my bench worse, for the fact that it is already progressing at turtle speed). I also believe in having nice looking palms

.
The 195kg x 5 that I pulled last week was an OK lift, the 5th rep witnessed a hitch but I tried to remain composed and managed a fine lockout. That would be a 50/50 decision in terms of technique. Although I believe that my failure this session was due to the lack of upper body mass, I also believe that I wasn't mentally prepared. Being able to pull 200kg x 5 RAW at 72kg is a big achievement in my book. I have been training with a coach for 3 months. Now I am on vacation, 3 months on my own and when I get back, its time to get totally serious, get in the top 10 or something. But thats not what I'm trying to convey here.
I faced the similar situation when I was moving my squats from 145kg x 5 to 150 x 5. Although it was only a 5kg transition, the fact that it was a 150 shook me up a little bit, making it similar to what I'm facing right now deadlifting 195kg and moving up to 200kg for 5 reps. I have to admit that I was disgustingly intimidated when I had 4x20kg plates and 1x10kg plate on each side. I went all psyched up ,took too long to setup, broke off the ground up to my knees and loss my tightness , BAM ! down the ground. I always believe that if you fail that set, don't bother attempting it again. Chances are that you will fail, very high.
I am a powerlifter wannabe, I have not competed yet, preparing myself for a big 2010, hopefully make through comps decently. There is also no excuses for my failure today, but I always believe in looking what I did right , THEN only look on what I did wrong. Today, there was some physical flaws that I must fix, not forgetting to prepare myself for a 2nd attempt hopefully next week or the week after.
I think everyone in this forum might benefit from whatever I've written a little bit here and there. No matter how experienced a lifter you are, sometimes we get drifted away and forget the basics.
