The Claim
In young women who train twice weekly for 8 weeks, incline biceps curls lead to greater improvements in incline curl strength (3RM) compared to preacher biceps curls, with a mean difference of 0.86 kg (95% CI: 0.10, 1.62 kg), suggesting that strength gains are specific to the trained movement pattern.
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.
If young women do incline bicep curls twice a week for 8 weeks, they’ll get stronger at that exact move compared to doing preacher curls — it’s like getting better at one exercise by practicing that one specifically.

Incline biceps curls are associated with greater improvements in incline curl strength (3RM) compared to preacher biceps curls in young women training twice weekly for 8 weeks, with a mean difference of 0.86 kg (95% CI: 0.10, 1.62 kg), indicating that strength gains are specific to the trained movement pattern.
What the research says
1 studyStudy: Distinct muscle growth and strength adaptations after preacher and incline biceps curls
The study found that women who did incline bicep curls got stronger at that specific curl compared to those who did preacher curls, which supports the claim.
