Ok to expand, it depends on what you're trying to use it for. You'll spend your time using it at 80-110% of your bench max.
1) Weak triceps - run through your triples with slightly less speed off the chest depending on how weak your triceps are you may need to start at 80% and work up.
2) Weak at the chest - pause on the chest for 1-2 seconds and drive off hard, same idea as the triceps, work from 80% up to gauge the weakness first.
3) Adapting to heavier loads - this will just happen as you handle these higher percentages
