The Claim
In young women undergoing resistance training twice weekly for 8 weeks, preacher biceps curls lead to greater increases in distal elbow flexor muscle thickness compared to incline biceps curls, with a mean difference of 0.10 cm (95% CI: 0.04, 0.15 cm), suggesting that muscle hypertrophy is regionally specific based on exercise selection.
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 preacher curls instead of incline curls during their workouts for 8 weeks, they’ll likely build more muscle in the lower part of their biceps.
See the scientific wording
In young women performing resistance training twice weekly for 8 weeks, preacher biceps curls are associated with greater increases in distal elbow flexor muscle thickness compared to incline biceps curls, with a mean difference of 0.10 cm (95% CI: 0.04, 0.15 cm), indicating that muscle growth is regionally specific to exercise selection.
What the research says
1 studyStudy: Distinct muscle growth and strength adaptations after preacher and incline biceps curls
The study found that preacher curls increased muscle size more near the elbow compared to incline curls, just like the claim says, so it supports it.
