1. ## Calculating 1 RM

How do you calculate your one rep max? I'm looking for the actual equation, not a calculator. thanks guys

2. Most of the 1RM calculators are not very accurate. There are many variables depending on the exercise and the individual.

Here is one chart that I have found to be somewhat helpful though:

It's not going to be exact for everyone so therefore no equation is going to be perfect. The online calculators all use some sort of equation, anyway. One of the more accurate that I've found is here:

4. it really depends on the individual, like the above have said.

if your endurance sucks but your pressing/pulling strength is good, your 1RM can be decently higher than any calculator (which is just a formula) will estimate

5. You calculate it by trying it.

6. ^^^This. Calculating is OK, but you'll never really know until you try.

Do you just keep loading up the bar with more and more weight until you can only do 1 rep? On what day should you try for it? At what time in your workout do you try it? How?

8. Calculate one rep max:
1) Get under bar
2) Lift bar
4) Repeat steps 1-3 until unable to complete step 2.
5) Write down last weight successfully lifted. (Done)

Except you don't get UNDER the bar as listed in step one
