The best easiest thing to do is lead up with slow increases, without getting too taxed as you approach the max.
Example appraoch...
#Empty bar x10-12
#135x5 warmups
#225x2
#275x1
#315x1
#335x1
#345x1 New PR
What lift is it? I am assuming the BP!?
Just make jumps that are manageable but not near maxes.
Start making maybe #50 jumps near or at wrmups then drop down to #20's then maybe #10's If you see the last rep go up, but go up slowly, make your next attempt with only 2-1/2 pounds!?
If you like coffee, have a good cup of joe, about a 1/2 hour or so before LOL
