The Claim

In recreationally trained women, there is no statistically significant difference in regional muscle hypertrophy patterns between preacher curls and inclined bicep curls following 9 weeks of resistance training, as evidenced by a non-significant group-by-region interaction (p = 0.367), indicating that the resistance profile of an exercise may not solely determine the regional distribution of muscle growth in this population.

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

For women who work out regularly, doing preacher curls or incline bicep curls doesn't seem to change where their biceps grow — both exercises lead to similar growth patterns after 9 weeks.

There is no statistically significant difference in regional muscle hypertrophy patterns between preacher curls and inclined bicep curls in recreationally trained women after 9 weeks of training, as indicated by non-significant group-by-region interaction (p = 0.367), suggesting that resistance profile alone may not determine where muscles grow in this population.

What the research says

1 study
  1. Study: Regional Hypertrophy: The Effect of Exercises at Long and Short Muscle Lengths in Recreationally Trained Women

    The study compared two bicep exercises in women and found no significant difference in where the muscles grew, which matches the claim.
