Thread: help with new sticky

ok, yes,i'm very green,the latest sticky tells me my 3 sets by 10 reps is wrong. at a weight you can do 10 times it is 75% of your 1 rep max, now, if the optimal rep total is 18=3 sets of 6 (with the same weight) how is this building muscle more than doing that weight @ 3x10? don't get me wrong, i don't know enough to argue the validity of things pertaining to lifting, i'm just trying to understand how doing the same weight less times is better.there is no time interval incorporated, so i don't "get it"

its's the top sticky "selecting the proper rep range" and i guess its not new, i saw the date wrong.I understand going to failure on 3 sets,sometimes i like to go 10,8,6 but i'm using 75% 1rm,80%1rm and 85%1rm. The chart gives the intensity range to use on 3x6 as 75%, which is a weight you can do 10 reps with, therein lies my confusssion-3x6@75% is better than 3X10 @75%?
