i am currently dropping 2 weight classes from the 105kg (at 25%BF) to the 83kg (im currently just under 200lbs at 15% or so) to see how much better i am while not being a fatty. What do you guys think is the best BF% for a powerlifter to be to have the best Wilks. Im thinking 10% would be pretty good. Any lower and your extreme dieting may start decreasing your strength.
