1 REP MAX EXPLAINED
1 Rep Max (1RM) is the maximum amount of weight an athlete can lift just one time or for a single “rep”.
This is a useful number to know to track your progress in a training program to see if. you are getting stronger, or to compare your strength to other athletes to see how you measure up.
Keep in mind while a 1 Rep Maximum (1RM) is a useful measure of athletic strength for a given lift, it has its limitations and may not be the only measure you want to optimize for in sports that require endurance, agility, flexibility, or skilled knowledge, and coordination.
For more information check out our detailed writeups about what a 1RM is, how it’s calculated, and the limitations of a calculated vs tested value.
