The Claim

In recreationally trained women, performing inclined bicep curls with an ascending resistance profile for 9 weeks, following a standardized protocol of 4 sets of 12 repetitions to failure three times per week, does not result in statistically significant regional hypertrophy of the biceps brachii or brachialis muscles at 50%, 60%, or 70% of the acromion-to-olecranon distance.

Description
1 study reviewed
In plain English

Doing a specific type of bicep curl on an incline with changing resistance doesn't seem to make certain parts of the upper arm muscles grow more in women who work out regularly — even after doing it consistently for 9 weeks.

See the scientific wording

In recreationally trained women, inclined bicep curls performed with an ascending resistance profile do not produce statistically significant regional hypertrophy in the biceps brachii or brachialis muscles at 50%, 60%, or 70% of the acromion-to-olecranon distance after 9 weeks of training, despite adherence to a standardized resistance program of 4 sets of 12 repetitions to failure three times per week.

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 found that doing inclined bicep curls didn’t make any part of the upper arm muscle bigger in women, which matches what the claim says.
