Around 2000 after we all realize the world was not going to end from Y2K I started a different training style.  While I still really loved going heavy I was always a little tired once I made it to my heaviest weights.  I decided to stop pyramiding up in weight and do just minimal warms ups to tackle my heaviest sets first.  I would gradually lighten the weights as I needed to hit my rep goals while finding that I was able to go much heavier than before.

For example:

Squats
135×10
225×5
315×5
425×4
395×5
355×4

Give reverse pyramiding a try for your big lifts or smaller ones too!  Let me know what you think.
