The performance standards are adult standards (>18 years
old) for a single maximal repetition (1RM) based on competitive
weightlifter and powerlifting classification systems in use from
the 1950's to present.
Submaximum loads may be used to estimate one rep maximum values
using the One Rep
Accumulated performance data is not predictive or regression
derived. These performance standards should not to be confused
with strength norms.
Standards are based on lifts with no assistive training gear
(belt is acceptable) as described in each lift's official international
competitive and/or as shown via link to exercise.
Training levels used in performance standards are as follows:
Tables for the basic barbell exercises are based on nearly
70 years of accumulated performance data and are not predicted
or regression derived. These performance standards should not
to be confused with strength norms.
