The Claim

Among healthy older men undergoing 16 weeks of heavy resistance exercise training, 82% are classified as robust or excellent responders across multiple muscle strength and hypertrophy outcomes, while only 5% are classified as poor responders, indicating that true non-response is rare.

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.

Description
1 study reviewed
In plain English

When older men who are healthy lift heavy weights for 16 weeks, most of them—82%—get much stronger and build more muscle, while barely 5% don’t improve much, so it’s rare for someone to not benefit at all.

What the research says

1 study
  1. Study: Heavy resistance exercise training in older men: A responder and inter-individual variability analysis

    The study looked at older men doing heavy weight training for 16 weeks and found that almost all of them got stronger and built more muscle — only a tiny few didn’t improve much. This matches exactly what the claim says.
