# Working Out Rep Max

Going by your rep max, how would you workout say, for example your 7 rep max?

Thanks for any help with the stupid question.

Here is a link to a one rep max calculator. Just plug in different numbers until you get the one rep max you want.

Repetitions Coefficient Percentage
1 1.000 1.00
2 1.047 .955
3 1.091 .917
4 1.130 .885
5 1.167 .857
6 1.202 .832
7 1.236 .809
8 1.269 .788
9 1.300 .769
10 1.330 .752
11 1.359 .736
12 1.387 .721
13 1.416 .706
14 1.445 .692
15 1.475 .678
16 1.504 .665
17 1.531 .653
18 1.560 .641
19 1.587 .630
20 1.616 .619

For example, multiplying a 10RM by 1.1330 will result in an estimated 1RM. Then multiplying that estimated 1RM by .809 will result in a very estimated 7RM.
