The Claim

Repetitions-in-reserve (RIR) prediction accuracy is not associated with biological sex, years of resistance training experience, or relative bench press strength in resistance-trained individuals.

What the research says

Supports is higher

Support is ahead, but a single strong opposing study can change this.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

In plain English

This claim says that how well people can guess how many more reps they have left in a workout doesn't depend on whether they're male or female, how long they've been training, or how strong they are at bench pressing relative to their body weight.

See the scientific wording

No relationship exists between repetitions-in-reserve (RIR) prediction accuracy and biological sex, years of resistance training experience, or relative bench press strength in resistance-trained individuals.

  1. Study: Accuracy of Intraset Repetitions-in-Reserve Predictions During the Bench Press Exercise in Resistance-Trained Male and Female Subjects

    The study looked at whether people's ability to predict how many reps they had left in a workout was affected by their gender, training experience, or strength, and found it wasn't—just like the claim said.
