The Claim
Incline biceps curls result in greater increases in muscle thickness at the 50% humeral length site—predominantly composed of the biceps brachii—compared to preacher curls, indicating superior biceps hypertrophy with incline curls.
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.
Doing bicep curls on an incline bench might build your biceps muscle better than doing preacher curls, especially in the middle part of your upper arm.
See the scientific wording
Incline biceps curls lead to greater muscle thickness increases at the 50% humeral length site, a region predominantly composed of biceps brachii, suggesting superior biceps hypertrophy compared to preacher curls.
What the research says
2 studiesStudy: Distinct muscle growth and strength adaptations after preacher and incline biceps curls
The study found that incline curls led to more muscle growth near the top of the biceps, which supports the idea that they build more biceps size in key areas compared to preacher curls.
Study: Distinct muscle growth and strength adaptations after preacher and incline biceps curls
The study found that incline curls build more muscle in the upper arm, especially in the area the claim talks about, so it supports the idea that incline curls are better for biceps growth there.
