What is 1rm?

1RM stands for "One Repetition Maximum" which refers to the maximum amount of weight an individual can lift for one repetition of a particular exercise. This is often used as a measure of an individual's strength and is commonly used in weight training programs to determine the appropriate amount of weight that should be used during training. In order to accurately determine 1RM, the individual must perform the exercise with proper form and technique and gradually increase the weight until they are unable to lift it for a single repetition. It is important to note that attempting to lift too much weight without proper preparation can be dangerous and may result in injury. Therefore, it is recommended to work with a trained fitness professional or spotter when attempting to determine 1RM.
