No but I deload when I'm overly annoyed with my form. Usually I go down 10 pounds.

i do it a lot, relatively. but i don't plan it, because what if a week came along when i needed it and it wasn't part of The Plan?

i deload when my form drifts and the weight's so heavy that i'm fighting too hard with that to put anything right. or when i'm tired. tbh, if my body wants me to deload it happens whether i planned it or not.

edit to answer less frivolously: i think it's good to leave room in your mind that sooner or later you'll want to deload. that way you'll be more likely to do it when you need to do it. but i find lifting is too up-and-down for just putting it into a schedule and leaving it there. i'm lifting on the wendler system now, which sets one week as 'deload' out of every four. it was fine for three or four cycles for me, b ut lately i'm finding myself less and less ready to start the next cycle when the sheet says i'm 'meant' to come out of deload. so it's a mmv thing.

I don't plan it. Life in general makes it happen. For example I'm going on vacation next month and won't be lifting for 11 days. I will bring my Kettlebell with to keep me in shape. When I get back I will deload 10-15%. This happens about 4 times a year.

I don't plan on it, but I have to take some time off because I had surgery friday to remove a few veins from my leg. I can't do any lifting that involves my legs. I am going to do much lighter benchpress and some other arm workouts and some light walking on the treadmill. I will really miss my routine. Hope I'm not out too long.
