1RM Testing Protocols for Rugby

How max strength is assessed safely and consistently

2 min readAdvanced

A one-repetition maximum (1RM) is the heaviest load a player can lift once with sound technique. Used well, 1RM testing anchors training percentages, monitors strength progress, and informs return-to-play decisions — but it is a coach-administered, supervised protocol, not a self-test, and is not appropriate for every athlete population.

What a 1RM is for

S&C coaches use a 1RM to anchor training percentages, compare players against position benchmarks, and track changes over time. Players see a number, but the coach is mostly interested in the trend and the technical quality of the lift.

What players notice during the protocol

  • A longer warm-up than a normal session — usually 15-25 minutes.
  • Progressive sets that get heavier and shorter in reps.
  • Two to three minutes of rest between top sets.
  • A spotter or safety bars on every working set.
  • A coach who will end the protocol early if form breaks down.

What players should not do

  • Test on a day with poor sleep or illness.
  • Hide a niggle to chase a number.
  • Skip the warm-up or rush the rest periods.
  • Compare your 1RM to a teammate's — body mass, leverages, and history all change the meaning.

How often it happens

Most clubs test 1RM 2-4 times per year — typically at the end of pre-season, mid-season, and end of season. In-season testing is usually estimated from sub-maximal sets rather than a true 1RM.
