When deciding whether to attempt a true one-repetition maximum (1RM) or a three-repetition maximum (3RM) or five-repetition maximum (5RM), individuals should consider several factors:
Testing Purpose: If the aim is to gauge progress or set training loads, a 3RM or 5RM can be indicative of strength levels without the risks associated with a maximal 1RM
Experience Level: Beginners may benefit from 3RM or 5RM tests to build confidence and technique, while more experienced lifters may be ready for a true 1RM.
Goals: If the primary goal is to increase maximal strength, a 1RM may be more relevant. For hypertrophy or general strength conditioning, 3RM or 5RM may be more suitable. https://strengthlevel.com/one-rep-max-calculator
Safety: Lifting at or near maximal capacity increases the risk of injury. If the lifter is unsure about their ability to safely attempt a 1RM, opting for a 3RM or 5RM is often safer. https://strengthlevel.com/one-rep-max-calculator
Fatigue Levels: If the lifter is fatigued or not feeling at their best, a 3RM or 5RM might provide a more achievable and safe option. https://strengthlevel.com/one-rep-max-calculator
Warm-Up and Recovery: Preparing for a true 1RM typically requires more extensive warm-up and recovery time. Lifters should consider their ability to commit to this.
Psychological Readiness: The mental aspect of attempting a 1RM can be significant. Lifters should assess their confidence and readiness for a maximal effort.
