Be forewarned this post is long with limited use information, all pertaining to estimating bodyweight + weight one-rep maxes. At the beginning of the month my weighted chins rep max looked like this with Jim Wendler's rep-max estimator in his 5/3/1 book:
Weight x Reps x .0333 + Weight = Estimated 1RM
(45 * 6 * 0.0333) + 45 = 53.99100
and happily enough I'm already back up to this:
(55 * 6 * 0.0333) + 55 = 65.98900
The numbers come out a little funny, but they represent progress. At weights so low, the one-rep maxes are obviously false (I can lift 55lbs for 6 reps but my estimated 1RM is 55.9lbs - really? So I decided to switch things up and include the obvious variable of my own weight in the equation. In an attempt to squeeze some damn sense out of these numbers for an accurate 1RM, my equation of bodyweight movement one-rep maxes with added weight looks like this:
Bodyweight + Weight x Reps x .0333 + Weight = Estimated 1RM
In this equation you only add your bodyweight variable to the first weight input so that you get an idea of the total amount of additional weight you can carry. I know my lowest bodyweight at any time this month was 165.5 so I'll use 165 as my weight (I know it's conservative but whatever, I'd rather not inflate these numbers for greater inaccuracy). So my January 4th and January 31st numbers now look like these, respectively:
(210 * 6 * 0.0333) + 45 = 86.95800
(220 * 6 * 0.0333) + 55 = 98.95600
And now it doesn't appear too screwed up to assumed I could add roughly 85lbs - 100lbs and get a rep in. That's fine, I don't need to know exactly how much my 1RM is (I don't take those numbers too seriously anyways) but I do like to know if I am still heading in the right direction. So, for my first reverse pyramid sets, I'm on the right track and I've helped everyone else in this thread who sucks at math like I do to make these calculations should they be so inclined.
