The Claim

In untrained females over an 8-week period, no significant differences were observed between high-volume (15-20 RM) and high-intensity (4-6 RM) resistance training protocols regarding muscle hypertrophy or strength development.

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

A study found that for women new to weightlifting, doing many reps with lighter weights or fewer reps with heavier weights both built muscle and strength equally well over 8 weeks.

See the scientific wording

No significant differences were found between high-volume (15-20 RM) and high-intensity (4-6 RM) resistance training protocols for either muscle hypertrophy or strength development in untrained females over 8 weeks, challenging the empirical assumption that different rep ranges preferentially target specific adaptations.

What the research says

1 study
  1. Study: Influence of two different modes of resistance training in female subjects.

    The study found that both high-rep and low-rep weight training gave women similar muscle growth and strength gains, supporting the claim that the rep range doesn't matter much for beginners.
