What is an estimated one-rep maximum (e1RM)?

Estimated one-rep max (e1RM)

In Volt, an estimated one-rep maximum is a set-by-set projection of the most weight an athlete can theoretically lift in a movement at a given time. e1RMs, unlike true 1RMs, are calculated during sub-maximal sets (with reps as high as 15+) and are used to recommend the most accurate loading possible for athletes during a workout, based on how they are feeling and performing that day. While a 1RM changes infrequently, and only when tested explicitly, an e1RM can change over the course of a single workout, making it a much more dynamic and timely measurement of an athlete’s strength in any given workout.

So, why is the e1RM important for Volt? Primarily, it’s because athletes are not the same from day today. For a true 1RM test, how you perform on the day of the test will affect your recommended loading for future workouts until you test your 1RM again. And if you aren’t feeling well or performed poorly for whatever reason during that 1RM test, the effectiveness of future workouts might suffer. Using an e1RM to recommend loading instead allows Volt to recommend the most accurate loading possible from set to set, helping to meet athletes where they are at on any given day. If athletes are completing Volt workouts as prescribed, their e1RM measurements should trend upward over time, though there might be fluctuations from set to set (or even workout to workout).
