Calculator Formula
This calculator uses the Epley formula to calculate your one rep max (1RM).
Here's the equation: 1RM = W x (1 + R/30)
What the hell does that mean? Let me break it down for you...
1RM: This is your one rep max
W: Weight lifted (bodyweight + extra weight)
R: The number of repetitions divided by 30
Plugging Numbers Into The Formula
As an example, I'll use someone who weighs 150 lbs, throws on a 20 lbs weight vest, and does 8 reps.
Plugging these numbers into the formula will look like this: 1RM = 170 (1 + 8/30)
So first I'll solve what's inside the parentheses --> 8/30 = 0.266, then add 1 = 1.266
Then multiply that by 170 to get a 1RM of 215 lbs.

I've shown you the formula and how you can plug in numbers but there's no need to rack your brain with all that math.
Plug your three numbers into the calculator and in a matter of seconds you'll get your estimated one rep max.
Now you'll have an idea of how much weight you can add on to your calisthenics.
And remember, this works for dips too.
