A 1-repetition maximum, often referred to as 1RM, is defined as the maximum amount of weight that an individual can successfully lift for one complete repetition of a specific exercise. This measure is crucial for assessing an individual’s strength level in that exercise and is commonly used in strength training programs to establish baseline strength and track progress over time.

The significance of the 1RM is that it provides a benchmark for individuals to gauge their strength capacity. It allows for the calculation of appropriate weights for various training programs, typically utilizing percentages of the 1RM for determining load during workout sessions.

In terms of the other options, while they address aspects of weight lifting, they do not accurately define the concept of 1RM. Lifting for multiple repetitions refers to a different performance measure, the minimum weight needed doesn't relate to the maximal effort associated with 1RM, and lifting without assistance describes a different scenario that does not directly pertain to one repetition maximum testing. The specificity of what a 1RM entails is crucial for both training and assessment purposes in fitness.
