Hi Fat Boi,
Cudd is right with his reply!
The answers are in your post.
Pre-fatigue exercises are exactly that: they fatigue the muscle being trained first before the main heavy exercise ie. Benchpress. The really important thing to remember here is that you are training to failure in the 8-12 rep range. So long as you are achieving this the weights will look after themselves, ie inrease as you get stronger!
Just remember to use correct form! It's all about the form especially when going to failure.
Good luck, Graham
