A few changes in my training :

I used to train at 95% of 1RM then I recently switched to 90% but when I tested my 1RM I found I didn't make progress, after 20 workouts curl is the same (no loss) and on floor press the Left Arm trained at 95% gained +1.5kg in 22 days and the Right Arm trained at 90% didn't gain (didn't loss either). In 2008 I tested multiple times 80%, 85% even 70% and I was only able to make regains, NO gains. In 2009 I tested 95% and 100%. 100% was too much I overtrained very quickly or had to use a frequency a la Heavy Duty (once every ~12-15 days) and thus the gains were slow. So now it appears clearly that 95% is the optimum load. The problem is that at 95% there is some fatigue which can be accumulated if frequency is too high. It's why I have to find what's the optimal frequency. I used to train everyday because some of my tests based on REgains showed that a very high frequency (every day or once every other day was the best) but I'll do further tests and this time on Gains not regains. I'll train like that :

Left Arm : Floor Press & Curl 95% 1/4 days
Right Arm : Floor Press & Curl 95% 1/2 days
Deadlift : 95% 1/2 days

If 1/2 is better than 1/4 then I'll test 1/2 vs 1/1 and in the contrary if 1/4 is egal to 1/2 I'll test 1/4 vs 1/6 or 1/8 days. After thoses test I'll have finish most of the tests I wanted to do.

On Deadlift I'll restart light and with a Straigth Back. I want to be able to DL in 30 years and if I continue like that I won't be able to DL at all. Rounded back DL fatigues too much the muscles of the back and when you attempt a rounded back DL with fatigued muscles the risk of injury is very high (which is not the case with fresh muscles). Yesterday I hurt my back, not too badly but enough to stop to use too heavy loads and crapy form. I'll forget the 200kg for now... but I'll be there slowly and safely, maybe quicker than I think... For the moment I'll take one week off and restart very light with a PERFECT form.
