The Claim

Some people’s muscles have a hidden gene pattern before training that’s linked to poor growth — it involves genes that control energy production, muscle structure, and how cells respond to signals.

In plain English

Some people’s muscles have a hidden gene pattern before training that’s linked to poor growth — it involves genes that control energy production, muscle structure, and how cells respond to signals.

See the scientific wording

Baseline expression of a novel gene network (PLIER LV7) negatively correlates with muscle hypertrophy after resistance training, and includes genes involved in mTOR signaling, mitochondrial biogenesis, and cytoskeletal regulation, pointing to a complex molecular signature of poor responsiveness.

What the research says

1 study

  1. Study: Muscle Transcriptional Networks Linked to Resistance Exercise Training Hypertrophic Response Heterogeneity.

    This study found that people’s muscle gene activity before starting weight training can predict how much their muscles will grow — some gene patterns mean you’re less likely to get bigger, even with the same workout.
