The Claim
In resistance training programs targeting elbow flexor muscle hypertrophy, single-joint exercises (such as biceps curls) should be prioritized over multi-joint exercises in the training prescription.
What the research says
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.
When people want to build bigger biceps, they should focus on bicep curls rather than compound movements like pull-ups that work multiple muscle groups at once.
See the scientific wording
In resistance training prescription for elbow flexors hypertrophy, single-joint exercises such as biceps curl should be emphasized over multi-joint exercises
What the research says
1 studyStudy: Single-Joint Exercise Results in Higher Hypertrophy of Elbow Flexors Than Multijoint Exercise
The study compared two types of exercises for the biceps muscle: a single-joint exercise (bicep curl) and a multi-joint exercise (dumbbell row). After 8 weeks, the bicep curl group grew their biceps muscles significantly more (11%) than the dumbbell row group (5%), supporting the claim that single-joint exercises should be emphasized for elbow flexor hypertrophy.
