I've noticed that when I warm up, everything past 135 feels heavy. It doesn't matter if I'm doing a single with 150 lbs under my max, it still feels heavy. Last night I did 315 for 5 reps and it didn't feel like I could do any more. I then went up to 350 and did 5 with that. My depth was the same on both sets. You would think if I can do 5 with 350 then 315 should be easy to get 5 reps.
