Knowing your one rep max is a crucial step for starting any program based on one rep max percentages. Unfortunately, many popular novice programs don’t  have the lifter finding a one rep max, instead operating in higher rep ranges.

This spreadsheet allows the user to input 1-10RM (e.g. a 5RM) in order to estimate a 1RM.

Use this spreadsheet in 2 easy steps:

  1. Input the weight lifted
  2. Input the number of reps

And you’re ready to lift!
