Do Beginners Need to Test 1RM to Pick Weights?

The practical answer: you don’t need a tested 1RM

If you’re new to resistance training and wondering whether you must do a one-rep-max (1RM) test to choose your starting weight, the provided ACSM guidance emphasizes consistency and individualization. The excerpt also discusses intensity targets using %1RM examples, but it does not state that beginners must perform a measured 1RM test to set training loads.

What the guidance actually supports about 1RM

ACSM presents loading ideas in terms of percentages of 1RM (for example, heavier work for strength), but the provided excerpt doesn’t specify that a measured 1RM is required for beginners to choose training loads. Instead, it stresses that programs should be individualized for goals, enjoyment, and safety, and that meaningful results come from regularly doing resistance training.

What we can’t conclude from %1RM

So 1RM percentages can be a useful way to describe intensity, but the retrieved guidance doesn’t spell out whether beginners must test a true max to set weights. The evidence here supports individualized programming and goal-based loading ranges expressed as %1RM examples, but it doesn’t provide a specific beginner method for choosing loads without a measured 1RM.

What we know about 1RM testing safety—and what it doesn’t answer

One human study looked at injuries during 1RM testing in relatively healthy older adults (including people with no prior weight training). Across the full sample, most subjects completed 1RM testing without injury (97.6%), though some experienced injuries and many reported muscle soreness. The authors concluded that 1RM testing was an “acceptable tool” for strength evaluation in that older population, while noting that additional precautions may be needed for inexperienced, elderly individuals.

This matters for safety, but it does not establish what beginners “need” to choose training weights. It evaluated injury rates during testing, not whether testing is necessary or beneficial for beginner weight selection, nor does it reflect the broader beginner population you care about.

Bottom line for beginners

The provided ACSM excerpt emphasizes consistency and individualization and gives example loading targets expressed as %1RM, but it doesn’t state a requirement for beginners to measure 1RM before starting. The available human injury evidence focuses on what happened during 1RM testing in a specific older-adult group, and it doesn’t determine what beginners need to choose training weights.
