onerep

Onerep is a term used in resistance training to denote a single repetition of an exercise. A rep is the completion of one full movement from the starting position through the entire range of motion to the end position. In training programs, repetitions are organized into sets, such as three sets of eight reps or five sets of five, to structure work and rest.

Related to this is the concept of a one-repetition maximum (1RM), which is the maximum weight that can be lifted for a single repetition with proper form. 1RM is commonly used to set training loads, estimate percentages for programming, and gauge strength progress. Because attempting a true 1RM can carry injury risk, many practitioners estimate it from submaximal lifts using formulas such as Epley, Brzycki, or Lombardi; for example, the Epley formula estimates 1RM as weight × (1 + reps/30).

In practice, reps and load are chosen based on training goals—strength, hypertrophy, or endurance—along with factors like experience, technique, and recovery. Proper form, progressive overload, and adequate rest are essential to safe and effective training.

In other contexts, Onerep may refer to OneRep, a privacy-protection company that helps individuals remove personal information from data broker sites and limit online exposure. This use is unrelated to fitness terminology and represents a separate application of the name.
