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