I don't know how many people actually read the articles on this website but the "Simple Workout Tips" article by Mike Robertson of T-Nation addresses a "planned deload week." This is a direct quote from the article:
"1. Use a planned deload week
This is an argument that never seems to go away. One guy swears he needs to deload every fourth or sixth week. Another says he never takes planned deloads and just "listens to his body."
Here's what I've found: The guy that takes a planned deload tends to see longer and more consistent gains. He's banged up less often, and as a whole, enjoys lifting more.
The other guy, however, tends to push and push until he ends up injured. This leads to an unplanned deload week, when his body has finally had enough and tells him he has to take a break or risk serious injury.
Which guy would you rather be?"
I recognize and respect him as an experienced lifter and trainer so this completely washes away my argument of not taking planned rest periods....
So as I said, how you lift is a matter of preference and everyone has a different body so stick with what you trust and respond to.
