Well NO ONE can say what is the best approcah for you. Shoot most even are hard pressed to tell he best for them.
The idea is to be warm, ready for a high load, but still 100% fresh.
Just an example for ease we'll say your goin for 200 on bench.
start with the
bar x 15-20.
95 x 5
135 x 3
155 x 1
185 x 1
200 x 1
Rest between 2 mins or more You can also strecct it out a boit further in the singles. I just didnt feel like typing it all down for a example. LOL
Experiment and find what bests works for you.
Hope that helps,
