RPE and Percentage Chart (Free)
Two charts: percent of 1RM by reps, and RPE by reps. Enter a 1RM to see loads in every cell.
Percent of 1RM by reps
Source: NSCA Training Load Chart, adapted from Landers, J. Maximum based on reps. NSCA Journal 6(6):60-61, 1984 (PDF).
RPE chart (% of 1RM)
Source: the RPE chart developed by Mike Tuchscherer for the Reactive Training Systems (RTS) manual; Tuchscherer describes it as a guide to be customized for each lifter (RTS article). Values are the commonly reproduced version of the RTS chart. RPE 10 = no reps left, 9 = one left, 8 = two left.
How it works
Each cell is a percent of your 1RM. With a 1RM entered, each cell also shows that percent of your 1RM rounded to the nearest 5 lb or 2.5 kg. Both charts are averages; your numbers can differ by lift and training history.
